    For a first order reaction, \[A\xrightarrow[{}]{}\] Products, the half-life is 100s. The rate constant of the reaction is

    A)  \[6.9\times {{10}^{-2}}{{s}^{-1}}\]

    B)  \[6.93\times {{10}^{-4}}{{s}^{-1}}\]

    C)  \[6.93\times {{10}^{-3}}{{s}^{-1}}\]

    D)  \[6.93\times {{10}^{-1}}{{s}^{-1}}\]

    Correct Answer: C

    Solution :

                     For first order reaction, Rate constant, \[k=\frac{0.693}{{{t}_{1/2}}}\]                                 \[=\frac{0.693}{100}\]                                 \[=6.93\times {{10}^{-3}}\,\,{{s}^{-1}}\]
