    \[C{{H}_{3}}COO{{H}_{(l)}}+{{C}_{2}}{{H}_{5}}O{{H}_{(l)}}\] ⇌ \[C{{H}_{3}}COO{{C}_{2}}{{H}_{5\,(l)}}+{{H}_{2}}{{O}_{(l)}}\]  In the above reaction, one mole of each of acetic acid and alcohol are heated in the presence of little conc. \[{{H}_{2}}S{{O}_{4}}\]. On equilibrium being attained [CPMT 1985; MP PET 1992]

    A)                 1 mole of ethyl acetate is formed

    B)                 2 mole of ethyl acetate are formed

    C)                 1/2 moles of ethyl acetate is formed

    D)                 2/3 moles of ethyl acetate is formed

    Correct Answer: D

    Solution :

              In presence of little \[{{H}_{2}}S{{O}_{4}}\] (as catalyst) about 2/3 mole of each of \[C{{H}_{3}}COOH\] and \[{{C}_{2}}{{H}_{5}}OH\] react to form 2/3 mole of the product at equilibrium.
