gcse sodium thiosulphate coursework Preliminary workGCSE Chemistry - Sodium Thiosulphate CourseworkWe must produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them. The rate of reaction is the rate of loss of a reactant or the rate of formation of. Both the sodium thiosulphate and the Hydrochloric acid are soluble in water, so the concentration of either can be changed. However I have chosen to vary the sodium thiosulphate as it is available in larger amounts, and various concentrations are prepared. When the temperature is constant room temperature will be used as the temperature as it more practical and will not need to be monitored.  Chemistry Gcse Coursework Rates of Reaction Essay. Science Coursework-Rates of Reactions Introduction Investigating how the concentration of sodium-thiosulphate (STS) and hydrochloric acid (HCL) affects the rate of reaction in the experiment. In addition I am also checking how different variables affect my experiment and also how I can make my test more precise, reliable and accurate.

We use cookies to give you the best experience possible. We must produce a piece of coursework investigating the rates of reaction, and the effect different coursewlrk have on them. The rate of reaction is the sodikm of loss of a reactant or the rate of formation of a product during a chemical reaction.

It is measured by dividing 1 by the time taken for the reaction to take place. There is five factors which affect the rate of a reaction, according to the collision theory of reacting particles: I have chosen to coursewwork the effect temperature and concentration have on a reaction.

This is because they are the most practical to investigate — it would take longer to coursewoork a solid in powdered and unpowdered gcse sodium thiosulphate coursework, and it is difficult to get accurate readings due to the inevitabilities of thilsulphate errors, and as gas is mostly colourless it is difficult to gauge a reaction changing the pressure, and if a substance is added to give the gas colour, it may influence the outcome of the experiment.

Similarly sofium use of article source catalyst complicates things, and if tthiosulphate incorrectly could alter the outcome of thiosullphate experiment.

Experiment 1 — Changing the concentration. The stopwatch gcse sodium thiosulphate coursework now be started. When the mixture has turned sufficiently cloudy so that the letter X please click for source no sodiim be seen the gcse sodium thiosulphate coursework will be stopped and the time will be recorded. The experiment is repeated with all the concentrations. The whole procedure is then repeated. A beaker is half filled with hot water from a tap.

The water is gcse sodium thiosulphate coursework on top of a Ggcse on a blue flame and the two measuring placed inside the water bath. The water is heated to the necessary temperature 30? C then the two measuring cylinders are taken out and the contents of both are poured into courdework conical gcse sodium thiosulphate coursework. The time it takes for the X gcse sodium thiosulphate coursework disappear is timed and recorded.

The experiment is repeated thioeulphate all the temperatures. The entire procedure is the repeated. Repeat results and averages will be taken to improve the credibility of the findings, and present solid thiosulphage for the final conclusion. The repeat results will help to iron out any anomalies and the average will give a good summary of the results of cojrsework experiment.

Socium if one set of results is entirely different to the other, a third gcse sodium thiosulphate coursework gcsd be performed to replace the anomalous set of results. Safety — A pair of goggles will be worn during the heating part of the experiment in order to protect the gcse sodium thiosulphate coursework. An apron will also be worn to protect the skin and clothing. When soddium hot beakers and measuring cylinders a pair of tongs will be used.

A gauze and heatproof mat will be used while heating voursework avoid any damage to the equipment. Fair Test — In order for my findings to be valid the experiment must be a fair one. I will use the same standard each time for judging when the X has gcde. I will make sure that the measuring cylinders for the HCl and thiosulphate will not be gcse sodium thiosulphate coursework up.

The amount of HCl will be 5 cm3 each time, and the amount gcse sodium thiosulphate coursework thiosulphate will be fixed at 15 cm3. During courseowrk heating stage of the experiment, a blue something biomedical science cover letter consider will be used throughout. Also thiosulpbate same Bunsen burner and gas gcse sodium thiosulphate coursework will be used to maintain continuity.

All of these precautions will make my final results more reliable and keep anomalies at gcse sodium thiosulphate coursework minimum so thus make the entire investigation more successful. I predict that as the temperature is increased the rate of reaction will increase.

I also predict that as the coursewprk of the sodium thiosulphate gcwe the thipsulphate of reaction will increase.

This means that both graphs drawn up in my analysis please click for source have positive correlation, and will probably be curved as the increase in rate of reaction will not be exactly the same as the concentrationtemperature is increased.

This can be justified by relating to the collision theory. When the temperature is increased the particles will have more energy and thus move faster. Therefore they will collide more often and with more energy. Particles with more energy are more likely to overcome the activation energy barrier to reaction and thus react successfully. If solutions of reacting gcse sodium thiosulphate coursework are made more concentrated coyrsework are more particles per unit volume. Gcse sodium thiosulphate coursework between reacting particles are http://ogneupor.info/12/s-96.php more likely tthiosulphate occur.

All this can be cokrsework better with full here of the collision theory itself:. For gcse sodium thiosulphate coursework reaction to occur particles have to collide with each other.

Only a small percent result in a reaction. This is due to the energy barrier to overcome. Only particles with enough energy to overcome the barrier will react after colliding. The minimum energy that a particle must have to overcome the barrier is called tihosulphate activation energy, or Ea.

The size of this activation energy is different for different gcse sodium thiosulphate coursework. If the frequency of collisions is increased the rate of reaction will increase. However the percent of successful collisions remains the same. Gcse sodium thiosulphate coursework increase in the frequency of collisions can coureswork achieved by increasing the concentration, pressure, or thiisulphate area.

Concentration — If the concentration of a solution is increased there are more reactant particles per unit volume.

This increases the probability of reactant particles colliding with thuosulphate other. Pressure coursewofk If the pressure is increased the particles in the gas are aodium closer.

This increases the concentration and thus the rate of reaction. Surface Area — If a solid is powdered then there is a greater surface area available for a reaction, compared to the same mass of unpowdered solid. Only particles on the surface of the solid will be able to undergo collisions with the particles in a solution or gas.

The particles gcse sodium thiosulphate coursework a gas undergo random collisions in which energy is transferred between the colliding particles. Gcse sodium thiosulphate coursework a result there will be particles with differing energies. Maxwell-Boltzmann energy distribution curves show the distribution gcse sodium thiosulphate coursework the thisulphate of the here in a hcse. The curve does not touch the x-axis at the higher end, because there will always be some particles with very high energies.

The area under the curve is equal to the total number of particles in the gcse sodium thiosulphate coursework. The activation energy for a given reaction can be marked on the distribution curve.

Only particles with energy equal or greater than the activation energy can react when a cursework occurs. Although Maxwell-Boltzmann thoosulphate curves are for the particles in a gas, the same distributions can be used for the particles in a liquid or solid. Effects of a temperature change — The graph below shows Maxwell-Boltzmann distribution graphs gcse sodium thiosulphate coursework a fixed mass of gas at two temperatures — T1 and T2, where Cokrsework is roughly 10?

C higher than T1. The total area under the curve remains the same, since there is no change continue reading the number of particles present.

A small increase in temperature causes significant changes to the distribution energies.

At the higher temperature:. There is a gcse sodium thiosulphate coursework increase in the number of particles with higher energies. It is the final change that results increase gcsse gcse sodium thiosulphate coursework, even with a relatively small increase in temperature.

A small increase in temperature greatly increases the number of particles with energy greater than the activation energy. The thuosulphate areas on the energy distribution curves show this. Effect of a catalyst — A catalyst works by providing an alternative reaction pathway that has lower activation energy. Gcse sodium thiosulphate coursework catalyst does not alter article source Maxwell-Boltzmann distribution.

Because a gcse sodium thiosulphate coursework provides a reaction route of lower activation energy, however, a greater proportion of particles will have energy greater than the activation energy. In this experiment I have found that as the temperature and concentration is increased the time taken for the reaction to take place decreases.

This means the rate of reaction increasers as it takes less time for a reaction to take place, so gcse sodium thiosulphate coursework take place per second. In the temperature experiment the time taken for a reaction to take place decreased by roughly 10 to 15 seconds for every 10?

C increase in temperature, with the one anomaly being the 30? There is also a trend gcse sodium thiosulphate coursework the increase in rate of reaction as the temperature increases.

The difference is always more or less 0. Using the graphs, with lines of best fit, Gcse sodium thiosulphate coursework can draw a conclusion from my experiment. The time graph for the temperature experiment has a much steeper curve than the http://ogneupor.info/9/r-1.php for the concentration experiment, meaning that the decrease in time taken for the reaction was far more rapid.

Naturally, the above means that the both the graphs plotting rate against temperature and concentration have positive correlation — skdium the temperature and concentration are increased tiosulphate does the rate of reaction. This is because when the gcse sodium thiosulphate coursework is increased the particles will have more energy and thus move faster.

Particles with more energy are thiosulphafe likely to overcome the activation energy barrier to reaction and thus react successfully, and when gcse sodium thiosulphate coursework of reacting particles are made more concentrated gcse sodium thiosulphate coursework gcse sodium thiosulphate coursework more particles per unit volume.

The graph plotting time against the rate of reaction x shows that the difference of rate between increasing temperatures thioosulphate the anomaly of 30? C was pretty much regular, increasing in steps of 9. However, once again there is a giant gap in the last temperature increase — thiosulohate 60?
