Catalysts lower the activation energy of reactions without being used up in the reaction. Since they lower activation energy, they also increase the rate of reaction. Catalysts are important because they can increase reaction rates of desirable reactions. For example, catalytic converters in cars can quickly convert harmful carbon monoxide to carbon dioxide with the use of a catalyst.
