Rate of reaction Plan Aim: Our aim of this experiment is see the effect of Sodium Thiosulphate and Hydrochloric Acid by testing different concentrations and looking at how it affects the rate of reaction. For my chemistry GCSE course work I am going to look at the factors that affect the rate of reaction. It can be changed by 4 main factors: Catalyst, Temperature, Surface area and Concentration. To increase the rate of a reaction you need to increase the number of successful collisions. The equation for this experiment is How Catalysts effect the rate of reaction What is a catalyst? A catalyst is a substance, which speeds up a reaction, but is chemically unchanged at the end of the reaction. When the reaction has finished, you would have exactly the same mass of catalyst as you had at the beginning. To increase the rate of a reaction you need to increase the number of successful...
