Vedclass · Answer

(D) Heterogeneous catalysis is a process where the catalyst exists in a different physical phase than the reactants.In the hydrogenation of vegetable oil,the reactant (vegetable oil) is in the liquid phase,while the catalyst $(Ni_{(s)})$ is in the solid phase.Since the phases are different,this is an example of heterogeneous catalysis.In options $A$,$B$,and $C$,the catalyst and the reactants are in the same phase (homogeneous catalysis).
