When the reactants are heated, the average kinetic energy of the molecules increases. This means that more molecules are moving faster and hitting each other with more energy. If more molecules hit each other with enough energy to react, then the rate of the reaction increases.
1 Heat energy causes some of the reactants to evaporate, increasing the concentration of the reactants. 2  Heat energy helps to lower the amount of overall energy that is required for the reaction to occur. 3  Heat energy increases the size of the molecules of reactants, and therefore the molecules react more frequently.
