    The standard Gibb's free energy change, \[\Delta G{}^\circ \] is related to equilibrium constant, \[{{K}_{P}}\] as

    A) \[{{K}_{P}}=-RT\] In \[\Delta {{G}^{{}^\circ }}\]

    B)   \[{{K}_{P}}={{\left[ \frac{e}{RT} \right]}^{\Delta {{G}^{{}^\circ }}}}\]

    C) \[{{K}_{P}}=-\frac{\Delta G}{RT}\]                   

    D) \[{{K}_{P}}={{e}^{-\Delta {{G}^{{}^\circ }}/RT}}\]

    Correct Answer: D

    Solution :

    [d] \[\Delta G=-RT\]ln \[{{K}_{P}}\] or \[{{K}_{P}}={{e}^{-\Delta G/RT}}\]
