    The standard Gibbs free energy change, \[\Delta {{G}^{o}}\] is related to equilibrium constant, \[{{K}_{P}}\] as

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

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

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

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

    Correct Answer: D

    Solution :

     Standard free energy, \[\Delta {{G}^{o}}\] and equilibrium constant, \[{{K}_{p}}\] are related as \[\Delta {{G}^{o}}=-RT\] In \[{{K}_{P}}\] In \[{{K}_{P}}=-\frac{\Delta {{G}^{o}}}{RT}\] \[{{K}_{P}}={{e}^{-\Delta {{G}^{o}}/RT}}\]
