JEE Main & Advanced Chemistry Surface & Nuclear Chemistry / भूतल और नाभिकीय रसायन Question Bank Catalyst and Catalysis

  • question_answer
    Formation of ammonia from \[{{H}_{2}}\] and \[{{N}_{2}}\] by Haber's process using \[Fe\] is an example of       [J & K 2005]

    A)                 Heterogeneous catalysis                             

    B)                 Homogeneous catalysis

    C)                 Enzyme catalysis                             

    D)                 Non-catalytic process

    Correct Answer: A

    Solution :

               The catalytic process in which the reactants and the catalyst are in different phases is known as heterogenous catalysis.                    \[{{N}_{2(g)}}+3{{H}_{2(g)}}\xrightarrow{Fe(s)}2N{{H}_{3(g)}}\]                                 The reactants are in gaseous state while the catalyst is in solid state.
