Question

What are catalysts ???
✌️✌️​

Answer 1

Explanation:

Catalysis is the process of altering the rate of a chemical reaction by adding a substance known as a catalyst. Catalysts are not consumed in the reaction and remain unchanged after it. Often only very small amounts of catalyst are required.

make me brainlist please✌✌

Answer 2

Answer:

Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed.

Explanation:

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. Enzymes are proteins that act as catalysts in biochemical reactions.

• Catalysts permit an alternate mechanism for the reactants to become products, with a lower activation energy and different transition state. A catalyst may allow a reaction to proceed at a lower temperature or increase the reaction rate or selectivity.
