    Unit of rate constant for 2nd order reaction is:

    A) \[mole\text{ }{{L}^{-1}}\text{ }{{\text{s}}^{-1}}\]                 

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

    C) \[{{\text{s}}^{-1}}\]                            

    D) \[mol{{e}^{-1}}\text{ }{{L}^{2}}\text{ }{{\text{s}}^{-1}}\]

    Correct Answer: B

    Solution :

    [b] \[Rate,\frac{dx}{dt}=k{{(conc)}^{n}}\] Units for 2nd order,                         \[n=2\]                         \[=L\,mo{{l}^{-1}}{{s}^{-1}}\] In case of gaseous reaction, unit is \[at{{m}^{-1}}{{s}^{-1}}\]
