Answer 2

Answer:

In chemistry, heterogeneous catalysis is catalysis where the phase of catalysts differs from that of the reactants or products.[1] The process contrasts with homogeneous catalysis where the reactants, products and catalyst exist in the same phase. Phase distinguishes between not only solid, liquid, and gas components, but also immiscible mixtures (e.g. oil and water), or anywhere an interface is present.
