The effect of temperature on the rate of a chemical reaction by Ben Luke 10G When sodium thiosulphate is mixed with dilute hydrochloric acid a yellow precipitate of sulphur is formed and the mixture goes cloudy Sodium thiosulphate + hydrochloric acid sodium chloride + sulphur dioxide + water + sulphur Na2S2O3 + 2HCl 2NaCl + SO2 + H2O + S The reaction can be followed by measuring the intensity of the cloudiness produced by the precipitate of the sulphur. We are going to find the effect of a change in temperature of the reacting solutions on the rate of reaction. Prediction I predict that as the temperature increases the rate of reaction will increase. This is because the temperature increases the energy of the molecules, this is shown in graph A In order to form a new substance, the molecules need to be at an energy level where they can break the bond. Graph B shows this. In Graph...
