Answer the question on the basis of passage given below :
Adsorption is a surface phenomenon and it differs from absorption which occurs throughout the body of the substance that absorbs. In physiosorption the attractive forces are mainly van der Waal's forces while in chemisorption ionic/covalent bonds are formed between particles of adsorbent and adsorbate. The catalytic activity of finely divided iron in Haber's process of ammonia manufacture can be explained by adsorption theory. Adsorption being an exothermic process, the heat of adsorption is utilised in enhancing the rate of the reaction. Adsorption has many applications being used in gas masks, control of humidity, chromatograph separation, curing diseases etc.
The modern adsorption theory lists the following steps for heterogeneous catalysis
(A) Adsorption of reactant molecules on the surface of a catalyst
(B) Occurrence of chemical reaction on the surface of a catalyst
(C) Desorption of products from a catalyst surface
(D) Diffusion of reactants to the surface of the catalyst
