    Time required for 100 per cent completion of a zero order reaction is

    A)  \[\frac{2k}{a}\]

    B)  \[\frac{a}{2k}\]

    C)  \[\frac{a}{k}\]

    D)  \[ak\]

    Correct Answer: C

    Solution :

    For zero order reactions, \[[A]=-kt+{{[A]}_{0}}\] where, \[{{[A]}_{0}}\] = initial concentration \[=a\] [A] = remaining concentration \[=a-a=0\] On putting values of \[{{[A]}_{0}}\] and [A], we get \[t=\frac{a}{k}\]
