Aim: To find out how temperature affects the rate of reaction between dilute hydrochloric acid and Magnesium. Prior Knowledge/Prediction: The rate of reaction is the rate at which the reaction happens i.e. its speed. There are a number of things that can influence the rate of reaction: - Concentration Surface Area Catalysts Temperature Pressure Light I have chosen temperature. For a reaction to happen molecules must collide with each other. When they do, they have to have enough energy to cause a reaction. The amount of energy needed to cause a reaction is called the activation energy. Temperature helps to pass the activation energy by giving the molecules enough kinetic energy to break the energy barrier (The level of energy needed to start a reaction). So therefore by giving molecules more energy it means more particles are likely to have the activation energy. There are some theories that affect temperature and the rate of reaction. These are kinetic theory, collision theory...
