CORE DEFINITION

Catalysis (kə-TAL-iss-iss) is the increase in rate of a chemical reaction due to an added substance known as a catalyst ( KAT-əl-ist). Catalysts are not consumed by the reaction and remain unchanged after the reaction. If the reaction is rapid and the catalyst is recycled quickly, a very small amount of catalyst often suffices; mixing, surface area, and temperature are important factors in react

Anchor fast decisions

A catalyst provides a reaction pathway with lower activation energy, thereby accelerating the rates of both forward and reverse reactions, while its own mass and chemical properties remain unchanged before and after the reaction (it does not appear in the net reaction). It changes 'how quickly equilibrium is reached' but does not alter the position of equilibrium itself.
