A Homogeneous Catalyst exists in the same physical state as that of the reaction it catalyzes.

Explanation:
Catalysts are classifies as follow,
1. Homogeneous Catalyst
2. Heterogeneous Catalyst

Homogeneous Catalyst are those which are in same phase as that of reactants are.

Example:

Acetic Acid + Ethanol + H₂SO₄ → Ethyl Acetate + H₂O + H₂SO₄

In this reaction catalyst and reactants all are in same phase i.e. Liquids.

Heterogeneous Catalyst are those which are in different phase as that of reactants are.

Example:

Ethene + H₂ + Ni → Ethane + Ni

In this reaction ethene and hydrogen are gases while Nickle catalyst is in solid state.
