What kind of catalyst is always in the same physical state as the reactant?

A) Heterogeneous catalyst
B) Iron catalyst
C) Homogeneous catalyst
D) Chemiluminescent catalyst

Homogeneous Catalyst

A catalyst that is in the same phase (solid, liquid, or gas) as the reactants, facilitating the reaction uniformly.

Physical State

The physical state refers to the distinct forms that different phases of matter take on, primarily solid, liquid, and gas.

Reactant

A substance that undergoes chemical changes in a reaction.
