WebA catalyst is a substance that: increases the rate of a reaction. does not alter the products of the reaction. is not chemically changed or used up at the end of the reaction. Only a very small ... 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 …
