Answer

Brief Explanations:

Catalysts work by providing an alternative reaction pathway with a lower activation - energy. They do not combine with reactants to make them harmless, do not increase the energy needed for the reaction, and since the catalysts (platinum, palladium, rhodium) are solids and the reactants are gases, it is a heterogeneous catalyst.

Answer:

It provides an alternative pathway for the reaction.
