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