    Formation of ammonia from \[{{\text{H}}_{\text{2}}}\]and \[{{\text{N}}_{2}}\]by Haber's process using Fe is an example of

    A)  heterogeneous catalysis

    B)  homogeneous catalysis

    C)  enzyme catalysis

    D)  non-catalytic process

    Correct Answer: A

    Solution :

     In heterogeneous catalysis, the reactant and the catalyst are in different phases. \[{{N}_{2}}(g)+3{{H}_{2}}(g)2N{{H}_{3}}(g)\] In the Haber's process the reactants are is gaseous phase while catalyst (Fe) in solid phase.  Hence, it is an example of heterogeneous catalysis.
