Step-by-step solution

(A) In physisorption, the enthalpy heat is low and lies between 20   -   40   kJ   mol - 1 . In physisorption, multilayers of adsorbed particles are formed. (B) In chemisorption, the enthalpy heat is high and lies within the range of 40   -   200   kJ   mol - 1 . In chemisorption, a monolayer of adsorbed particles is formed. (C) N 2 g + 3 H 2 g ⟶ Fe ( s ) 2 NH 3 g Heterogeneous catalysts occupy a different phase. Generally, heterogeneous catalysts are solid compounds t
