    The rate constant of the reaction\[A\to B\]is \[0.6\times {{10}^{-3}}\]mole per second. If the concentration of A is 5 M, then concentration of B after 20 minutes is:

    A)  0.36 M

    B)  0.72 M

    C)  1.08 M

    D)  3.60 M

    Correct Answer: B

    Solution :

     For zero order reaction: \[x=K.t\]             \[=0.6\times {{10}^{-3}}\times 20\times 60\]             \[x=0.72\,M\]
