    A first order reaction has a rate constant \[W\]. How long it will take to decompose half of the reaction?

    A) \[\frac{4W}{3}\]              

    B) \[\frac{5W}{2}\]

    C) \[\frac{\pi }{2}\]  

    D) \[\sigma =\text{5}.\text{67}\times \text{1}{{0}^{-\text{8}}}\text{W}-{{\text{m}}^{\text{2}}}{{\text{K}}^{\text{-4}}}\]

    Correct Answer: C

    Solution :

                    \[\frac{3}{4}\text{m}/\text{s}\] \[\frac{1}{3}\text{m}/\text{s}\]                 \[\frac{3}{2}\text{m}/\text{s}\](for a first order reaction) \[\frac{2}{3}\text{m}/\text{s}\] \[{{\lambda }_{0}},\]
