    The unit is of the rate of a second order reaction is

    A)  \[tim{{e}^{-1}}\]          

    B)  \[mol\text{ }{{L}^{-1}}\text{ }tim{{e}^{-1}}\]

    C)  \[L\text{ }mo{{l}^{-1}}\text{ }tim{{e}^{-1}}\]   

    D)  \[{{L}^{2}}\text{ }mo{{l}^{-2}}\text{ }tim{{e}^{-1}}\]

    Correct Answer: B

    Solution :

    Rate of a second order reaction \[=\frac{change\text{ }in\text{ }concentration}{time}\] \[=\frac{mol\,{{L}^{-1}}}{time}=mol\,{{L}^{-1}}\,tim{{e}^{-1}}\]
