Catalysts lower the activation energy of a chemical reaction. Catalyst is a substance that speeds a chemical reaction. It is not consumed as the reaction proceeds. A catalyst offers a new route for faster reaction. Catalysts are classified as homogeneous (same state as the reactants) or heterogeneous (different state as the reactants). Platinum would be a heterogeneous catalyst. CFCs would be a homogeneous catalyst. Magnesium would be a heterogeneous catalyst.
