Experiment to Investigate the Effect of Changing Temperature on the Rate of reaction between Sodium Thiosulphate and Dilute Hydrochloric Acid. In this experiment, we shall be adding sodium thiosulphate to hydrochloric acid together and placing a drawn cross underneath and seeing how long the rate of reaction lasts until you cannot see the cross. Before the reaction starts, the liquids are both clear. When added they turn cloudy and milky with a yellow tinge to it, due to the sulphur released. Collision Theory The rate of reaction simply depends on how often and how hard the reacting particles collide with each other. The basic idea is that particles have to collide in order to react and they have to collide hard enough.> All chemicals are made from particles (atoms/molecules)> The particles have energy and can move> Chemical reactions only happen when particles collide> Some collisions are not successful. They must have enough energy...
