Acatalystis a substance that speeds up a chemical reaction, but is not consumed by the reaction; hence acatalystcan be recovered chemically unchanged at the end of the reaction it has been used to speed up, or catalyze. ...Catalystslower the energy barrier.

A catalyst is an agent or compound that is added to a process to make a chemical reaction happen more quickly. The catalyst can increase the reaction rate of the steam and can participate in the secondary reactions. The packing can also act as a catalyst to enhance desired chemical transformations.

Catalysis is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (/ˈkætəlɪst/), which is not consumed in the catalyzed reaction and can continue to act repeatedly. Because of this, only very small amounts of catalyst are required to alter the reaction rate in principle.
