    The unit of rate constant for- a zero order reaction is                                        [AIPMT (M) 2011]

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

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

    C) \[{{\text{L}}^{\text{2}}}\,\text{mo}{{\text{l}}^{\text{-2}}}\,{{\text{s}}^{\text{-1}}}\]

    D) \[\,{{\text{s}}^{\text{-1}}}\]

    Correct Answer: A

    Solution :

    [a] For zero order reaction, Rate = k -[Reactants]0
    \[\therefore \]Rate\[=k\]and unit of \[k=mol\,{{L}^{-1}}{{s}^{-1}}.\]
