    The unit of rate constant for second order reaction is

    A) \[{{s}^{-1}}\]

    B) \[mol/{{L}^{-1}}\]

    C) \[L\,\,mo{{l}^{-1}}{{s}^{-1}}\]    

    D) \[{{L}^{2}}mo{{l}^{-2}}s\]

    Correct Answer: C

    Solution :

    Unit of rate constant for nth order reaction is \[{{L}^{n-1}}\,\,mo{{l}^{1-n}}\,\,{{s}^{-1}}\] where, n = order of reaction For, second order reaction \[n=2\] \[\therefore \] Unit of rate constant for second order reaction is \[L\,\,mo{{l}^{-1}}\,{{s}^{-1}}\]
