GCSE Chemistry Coursework Rates of Reaction Aim: To investigate how one variable affects the rate of reaction Tom Anderson Year 10 KBY Rates of Reaction Coursework To investigate how one variable affects the rate of reaction Background Information: The rate of a reaction is the speed at which reactants react to form a product. If there is a low rate of reaction it means that the molecules have less energy and therefore react at a slower speed. If there is a high rate of reaction it means that the molecules have a large amount of energy therefore react at a faster speed. There are a number of variables that affect the rate of reaction, they are: * Concentration * Temperature * Surface Area * Catalysts * Pressure Rates of Reactions are explained by the collision theory (reference 1): "For two substances to react, their particles must collide together. Every time such a collision occurs there is the chance of a chemical reaction. Anything that increases...
