Vedclass · Answer

(A) 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 on the surface of the catalyst.$3$. Occurrence of a chemical reaction on the catalyst surface through the formation of an intermediate.$4$. Desorption of reaction products from the surface.$5$. Diffusion of reaction products away from the surface.The adsorption of reactants on the active sites of the catalyst increases the local concentration of reactants on the surface,which increases the frequency of collisions and thus the rate of reaction. Additionally,the catalyst provides an alternative pathway with lower activation energy.
