Vedclass · Answer

(D) catalyst is a substance that increases the rate of a reaction by providing an alternative pathway with a lower activation energy $(E_a)$.In heterogeneous catalysis,the reactants and the catalyst are in different phases,and the reaction occurs on the surface of the catalyst.Statement $A$ is correct because catalysts lower the activation energy.Statement $B$ is correct as the catalyst often forms intermediate surface compounds with the reactants.Statement $C$ is correct because the adsorption of reactants on the catalyst surface is a key step.Statement $D$ is incorrect because the primary function of any catalyst is to change (specifically lower) the activation energy of the reaction.

Which one of the following statements is incorrect in the case of heterogeneous catalysis?
