Witrynacatalysis, in chemistry, the modification of the rate of a chemical reaction, usually an acceleration, by addition of a substance not consumed during the reaction. The rates of chemical reactions—that is, the velocities at which they occur—depend upon a number of factors, including the chemical nature of the reacting species and the external … WitrynaAdvantages. Catalysts speed up the rate of reactio, which saves money because the plant doesn't have to operate for as long to produce the same amount of product. Catalysts allow the reaction to work at a much lower temperature. This reduces the energy used up in a reaction which is good for sustainable development.
