    The incorrect expression among the following is:   AIEEE  Solved  Paper-2012

    A) \[\frac{\Delta {{G}_{system}}}{\Delta {{S}_{total}}}=-T\]  

    B) In isothermal process, \[{{w}_{reversible}}=-nRT\,\,\ell n\frac{{{V}_{f}}}{{{V}_{i}}}\]

    C) \[InK=\frac{\Delta {{H}^{o}}-T\Delta {{S}^{o}}}{RT}\]         

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

    Correct Answer: C

    Solution :

                 \[\Delta {{G}^{o}}=\Delta {{H}^{o}}-T\Delta {{S}^{o}}\] -RT lnK \[\Delta {{H}^{o}}-T\Delta {{S}^{o}}\] lnK \[=-\frac{\Delta {{H}^{o}}-T\Delta {{S}^{o}}}{RT}\]
