    In the relation\[C{{H}_{3}}-\underset{\begin{smallmatrix}  || \\  O \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{3}}\],the dimensional formula for k is

    A) \[[{{M}^{0}}LT]\]                             

    B) \[[{{M}^{0}}{{L}^{-1}}{{T}^{0}}]\]

    C) \[[{{M}^{0}}{{L}^{-1}}{{T}^{-1}}]\]                           

    D) \[[{{M}^{0}}L{{T}^{-1}}]\]

    Correct Answer: B

    Solution :

    \[431-\left\{ \frac{1}{2}(434)+\frac{1}{2}(242) \right\}\]Dimension of cot = (dimensionless) hence   \[231-217-121=-931kJmo{{l}^{-1}}\] \[\Delta {{H}^{o}}\]
