    Isomerization \[C{{H}_{2}}=CH-O-C{{H}_{2}}-C{{H}_{2}}-C{{H}_{3}}\,\,\to \,\,C{{H}_{2}}=CH-C{{H}_{2}}\]\[-C{{H}_{2}}-C{{H}_{2}}OH\] follows first order kinetics. The graphical representation is as under What is the value of [k/2.303]:

    A) \[10\,{{s}^{-1}}\]                    

    B) \[{{10}^{-2}}\,{{s}^{-1}}\]

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

    D) None of these

    Correct Answer: A

    Solution :

    For a first order reaction slope = \[-\frac{k}{2.303}\] or \[\frac{-6}{60\times 10}\,\,=\,\,-\frac{k}{2.303}\,\,=\,\,{{10}^{-2}}\,{{s}^{-1}}\]
