Catalysis
Catalysis is the increase in the
rate of a
chemical reaction due to the participation of an additional substance called a
catalyst . With a catalyst, reactions occur faster and require less
activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.
