Catalysis - Wikipedia
WEBCatalysis (/ k ə ˈ t æ l ə s ɪ s /) is the increase in rate of a chemical reaction due to an added substance known as a catalyst (/ ˈ k æ t əl ɪ s t /). Catalysts are not consumed by the reaction and remain unchanged after it.

Catalysts (video) | Catalysis | Khan Academy
WEBA catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction. A catalyst works by providing a different pathway for the reaction, one that has a lower activation energy than the uncatalyzed pathway.
Types of catalysts (article) | Kinetics | Khan Academy
WEBIncludes examples of enzymes, acid-base catalysis, and heterogeneous (or surface) catalysis. Key points. A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.
