    Which one of the following is wrongly matched?

    A) Saponification of \[C{{H}_{3}}COOC{{H}_{5}}\]- Second order reaction

    B) Hydrolysis of \[C{{H}_{3}}COOC{{H}_{3}}\]- Pseudo unimolecular reaction

    C) Decomposition of \[{{H}_{2}}{{O}_{2}}\]- First order reaction

    D) Combination of \[{{H}_{2}}\] and \[{{B}_{2}}\] to give HBr -Zero order reaction

    Correct Answer: D

    Solution :

    [d] \[{{H}_{2}}+B{{r}_{2}}\rightleftharpoons 2HBr\] is a 1.5 order reaction i.e., \[K=[{{H}_{2}}]{{[B{{r}_{2}}]}^{1/2}}\]
