Catalyst vs. Reagent: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 6, 2024
A catalyst speeds up a chemical reaction without being consumed, while a reagent is a substance used in a reaction and is consumed or altered during the process.

Key Differences

A catalyst is a substance that accelerates the rate of a chemical reaction without undergoing permanent chemical change itself. A reagent, however, is any substance used in a chemical reaction, usually undergoing chemical change.

Catalysts function by lowering the activation energy of a reaction, making it easier to occur. Reagents are directly involved in the chemical reaction, reacting with other substances.

After the reaction, a catalyst remains chemically unchanged and can be reused. In contrast, reagents are typically consumed or altered during the reaction.
