    If 'a' is the initial concetration of the reactant, the time taken for completion of the reaction, if it is of zero order, will be

    A)  \[{}^{a}/{}_{k}\]               

    B)  \[{}^{a}/{}_{2\,k}\]

    C)  \[{}^{2a}/{}_{k}\]                 

    D)  \[{}^{k}/{}_{a}\]   

    Correct Answer: A

    Solution :

    For a zero order reaction, \[t=\frac{1}{K}\,\left\{ \left[ {{A}_{0}} \right]-[A] \right\}\] When reaction is complete \[[A]=0\] Therefore,      \[t=\frac{\left[ {{A}_{0}} \right]}{K}=\frac{a}{K}\]
