    The unit of rate constant for a zero order reaction is

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

    B)  \[mol\,L{{s}^{-1}}\]

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

    D)  no unit

    Correct Answer: C

    Solution :

                    For nth order of reaction a general formula for the unit of rate constant is \[{{\left( \frac{mole}{litre} \right)}^{1-n}}\times {{\sec }^{-1}}\] \[\because \]For zero order reaction, \[n=0\] \[\therefore \]Unit of rate constant for zero order reaction is mole\[litr{{e}^{-1}}se{{c}^{-1}}\]or\[mol\,{{L}^{-1}}{{s}^{-1}}\].
