Vedclass · Answer

(C) In heterogeneous catalysis,the reactants and the catalyst are in different phases. $(A)$ Ammonia synthesis $(N_2(g) + 3H_2(g) \xrightarrow{Fe(s)} 2NH_3(g))$ involves gaseous reactants and a solid catalyst. $(B)$ Lead chamber process $(2SO_2(g) + O_2(g) \xrightarrow{NO(g)} 2SO_3(g))$ is a homogeneous reaction. $(C)$ Hydrogenation of vegetable oils $(R-CH=CH-R(l) + H_2(g) \xrightarrow{Ni(s)} R-CH_2-CH_2-R(s))$ involves liquid and gaseous reactants with a solid catalyst. $(D)$ Hydrolysis of methyl acetate $(CH_3COOCH_3(l) + H_2O(l) \xrightarrow{H^+(aq)} CH_3COOH(aq) + CH_3OH(aq))$ is a homogeneous reaction. Both $(A)$ and $(C)$ represent heterogeneous catalysis. However,in the context of standard chemistry problems,the hydrogenation of vegetable oils is the classic example of heterogeneous catalysis involving different phases of reactants (liquid oil and gaseous hydrogen).
