✒ A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

✒ An example of it is an enzyme, which is a naturally occurring catalyst responsible for many essential biochemical reactions.

✒ Catalysts can be classified into two types - homogeneous and heterogeneous.

• Homogeneous catalysts are those which exist in the same phase (gas or liquid ) as the reactants.
• Heterogeneous catalysts are not in the same phase as the reactants.
