Catalysis is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (/ˈkætəlɪst/). Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are important factors in reaction rate. Catalysts generally react with one or more reactants to form intermediates that subsequently give the final …
