    Point out the wrong statement :                 For a first order reaction

    A)                 Time for half-change \[({{t}_{1/2}})\] is independent of initial concentration

    B)                 Change in the concentration unit does not change the rate constant \[(K)\]

    C)                 Time for half-change \[\times \] rate constant \[=0.693\]

    D)                 The unit of \[K\] is \[mol{{e}^{-1}}{{\min }^{-1}}\]

    Correct Answer: D

    Solution :

                    Unit of K for Ist order reaction is \[Tim{{e}^{-1}}\].
