    The rate constant of a first order reaction is \[3\times {{10}^{-6}}\] per second and initial concentration is\[0.10\,\,M\]. Then the initial rate of reaction is:

    A) \[3\times {{10}^{-6}}m{{s}^{-1}}\]                           

    B) \[3\times {{10}^{-8}}m{{s}^{-1}}\]

    C) \[3\times {{10}^{-7}}m{{s}^{-1}}\]                           

    D) \[3\times {{10}^{-9}}m{{s}^{-1}}\]

    Correct Answer: C

    Solution :

    For first order reaction we know rate\[=K{{[conc]}^{n}}\] [Given\[\to K=3\times {{10}^{-6}}\]per second,\[con{{c}^{n}}\]\[=0.1M\]]                 \[=3\times {{10}^{-6}}\times 0.1\]                 \[=3\times {{10}^{-7}}m{{s}^{-1}}\]
