Vedclass · Answer

(B) In heterogeneous catalysis,the reaction occurs on the surface of the solid catalyst. First,the reactant molecules must diffuse from the bulk phase to the surface of the catalyst to undergo adsorption. After the chemical reaction occurs on the surface,the product molecules must diffuse away from the catalyst surface back into the bulk phase to allow for further reaction cycles.
