Question

Quizplus · Accepted Answer

A catalyst that is in a different phase from the reactants and products is called a heterogeneous catalyst. This is because the catalyst exists as a separate phase, such as a solid or liquid, while the reactants and products are in gaseous or liquid form. Homogeneous catalysts, on the other hand, are in the same phase as the reactants and products. Enzyme-type, protein, and exogenous are not types of catalysts but refer to specific characteristics or origins of a catalyst.
