    Unit of rate constant of zero order reaction is:

    A) \[tim{{e}^{-1}}\]

    B) \[mol\,\,li{{t}^{-1}}{{\sec }^{-1}}\]

    C) \[litre\,\,mo{{l}^{-1}}{{\sec }^{-1}}\]

    D) \[litre\,\,mo{{l}^{-1}}\sec \]

    Correct Answer: B

    Solution :

    Unit of zero order rate constant Rate\[=K{{[conc]}^{0}}\] \[K=Rate=\frac{\text{change}\,\,\text{in}\,\,\text{concentration}}{\text{time}\,\,\text{interval}}\]  \[\text{=}\frac{\text{Mol/litre}}{\text{second}}\] \[\therefore \]Unit of \[K\] is mole\[\text{litr}{{\text{e}}^{-1}}{{\sec }^{-1}}\]
