    The standard free energy change, \[\operatorname{AG}{}^\circ \]is related to equilibrium constant K as:

    A) \[\operatorname{Kp} =-RT\,\operatorname{I}\operatorname{n}\,AG{}^\circ \]

    B)   \[{{\operatorname{K}}_{p}}=\left( \frac{e}{RT} \right)\Delta {{G}^{o}}\]

    C) \[{{\operatorname{K}}_{p}}=\frac{-\Delta {{G}^{o}}}{\operatorname{RT}}\]               

    D) \[{{\operatorname{K}}_{p}}=e-\Delta {{G}^{o}}\left( \operatorname{RT} \right)\]

    Correct Answer: D

    Solution :

    \[\Delta G{}^\circ =-RT In\,{{k}_{p}}\] \[-\frac{\Delta G}{RT}=\ell n\,{{k}_{p}}\] \[\operatorname{Or}={{k}_{p}}={{e}^{-\Delta {{G}^{o}}/RT}}\]
