WebCatalysis. Catalysis is the phenomena of altering the velocity of a chemical reaction by the presence of a catalyst. The temperature at which the catalyst activity is maximum is the optimum temp richer. The excess energy that the reactant molecules must acquire to change into the product is the activation energy.
