Vedclass · Answer

(D) According to the adsorption theory of catalysis,the mechanism involves the following steps:$1$. Diffusion of reactants to the surface of the catalyst.$2$. Adsorption of reactant molecules onto the surface of the catalyst.$3$. Formation of an intermediate on the surface,which leads to a decrease in the activation energy of the reaction.$4$. Desorption of products from the surface.$5$. Diffusion of products away from the surface.By adsorbing reactant molecules onto the active sites,the local concentration of reactants increases,which enhances the probability of collision and reaction,effectively lowering the activation energy path. Therefore,the correct statement is that the concentration of reactant molecules increases at the active sites of the catalyst.

According to the adsorption theory of catalysis,the rate of reaction increases because:
