WebA catalyst increases the rate of reaction by lowering the activation energy. A catalyst increases the rate of reaction in both forward and backward directions by providing an alternate pathway with lower activation energy. If the activation energy is reduced, more reactants can cross the energy barrier easily. So, the rate of reaction increases.
