What factors affect the rate of a chemical reaction? Plan I am going to investigate the reaction between sodium thiosulphate and dilute hydrochloric acid. The rate of this reaction can be changed by a number of things: * The temperature * The use of a catalyst in the reaction * The surface area (Of solid reactants) * The concentration of the reactants I will investigate the effect of varying the concentration of Sodium thiosulphate solution in a reaction with Hydrochloric Acid. In my preliminary tests I found that a mixture of Sodium thiosulphate and water totalling 50cm³ mixed with 10cm³ of Hydrochloric acid worked at the right type of speed for the time I have to do my experiment in, so these are the amounts I will use in the experiment. When sodium thiosulphate and hydrochloric acid are mixed together, yellowish sulphur is formed in the liquid, making the clear liquids cloud over. This is the equation for the...
