Chemistry Coursework Find the effect of temperature on the rate of reaction using :- Sodium thiosulphate + Hydrochloric acid Sodium chloride + Sulphur dioxide + Sulphur Plan The rate of reaction is the speed that the reaction occurs at. It can be effected by the following: o Concentration of reactants o Temperature o Surface area of reactants o Presence of a catalyst Out of those factors, I am going to investigate the effect temperature has on the rate of reaction. I will do this by recording the time it takes for the cross to disappear. I think that as the temperature increases, the rate of reaction will increase. The graph below shows what I think my results will look like. If you increase the temperature by 10°C, you approximately double the rate of many reactions. The reason why I think that increasing the temperature will cause the rate of reaction to increase is because of the collision theory. The collision theory says that the...
