    The unit of rate for a first order reaction is

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

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

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

    D)        \[mol\,\,{{s}^{-1}}\]

    Correct Answer: C

    Solution :

    Rate of a reaction\[=\frac{change\,\,in\,\,concentration}{time}\] \[\therefore \]units of rate\[=\frac{mol/L}{s}=mol\,\,{{L}^{-1}}\,\,{{s}^{-1}}\]
