THE RATES OF REACTION AIM Since my project is to investigate the rates of reaction, my aim is to test how one factor will affect the rate of reaction. BACKGROUND KNOWLEDGE The rate of reaction tells us how quickly a reaction takes place. The only real way to measure the rate of reaction is by implementing experiments. Usually the rate of reaction will vary if one factor variable has less or more volume. These are usually the variables that can affect the rate of reaction: - * Catalyst * Concentration on the reactants * Surface Area * Temperature These factors are variables, which if changed; it will affect the rate of the reaction. Catalyst A catalyst is a substance which speeds up a chemical reaction, leaving the catalyst unchanged after the reaction has taken place. Catalyst provides an alternative pathway for the reaction e.g. a catalyst that has much lower activation energy. More collisions will therefore have enough energy for...
