    Which one of the following is an example of homogeneous catalysis?

    A) Haber process of synthesis of ammonia

    B) Catalytic conversion of sulphur dioxide to sulphur trioxide in the contact process

    C) Catalytic hydrogenation of oils

    D) Catalytic conversion of water gas to methanol

    E) Acid hydrolysis of methyl acetate

    Correct Answer: E

    Solution :

    Homogeneous catalysis is that catalysis when the reactants, products and the catalyst are in the same physical state i. e. in the same phase. In the alternate (e) i. e., in the acid hydrolysis of methyl acetate, the reactants methyl acetate, products\[{{H}_{2}}O\]and catalyst (dil.\[HCl\]or dil.\[{{H}_{2}}S{{O}_{4}}\]acids) are in the same (liquid) phase. So, acid hydrolysis of methyl acetate is one of the example of homogeneous catalysis out of all other alternatives.
