$\ln K = \frac{\Delta H^{\circ} - T \Delta S^{\circ}}{RT}$

Vedclass · Answer

(B) The relationship between Gibbs free energy change and equilibrium constant is given by $\Delta G^{\circ} = -RT \ln K$.Substituting $\Delta G^{\circ} = \Delta H^{\circ} - T \Delta S^{\circ}$ into the equation,we get $\Delta H^{\circ} - T \Delta S^{\circ} = -RT \ln K$.Rearranging for $\ln K$,we obtain $\ln K = -\frac{\Delta H^{\circ} - T \Delta S^{\circ}}{RT} = \frac{T \Delta S^{\circ} - \Delta H^{\circ}}{RT}$.Comparing this with option $B$,we see that $\ln K = \frac{\Delta H^{\circ} - T \Delta S^{\circ}}{RT}$ is incorrect because the signs of $\Delta H^{\circ}$ and $T \Delta S^{\circ}$ are reversed.

The incorrect expression among the following is:
