Answer:
The correct answer is option D, They cause stronger bonds to form between molecules.
Explanation:
Heterogeneous catalysts are used for providing active reacting sites for the molecules. Usually the heterogeneous catalysts are used in a solid state with reactants in liquid and gaseous state. The reactant molecule get adsorbed on the surface of the catalyst and thus with the increased surface area, Â the rate of reaction also increases. Also being in a different phase than the reactants helps the catalysts to be easily separated with little expenditure.
