Chemistry - Thermodynamics - II Question with Solution | TestHub

The incorrect statement is C.

$\Delta G^{\circ }=0$ indicates equilibrium only under STANDARD conditions.

Option D is correct because the Gibbs Free Energy change ($\Delta G$) is negative for spontaneous processes like ice melting above 0°C (273 K) at 2 atm.

$\Delta G$ represents the maximum non-expansion work at constant temperature and pressure. When $\Delta G^{\circ }=0$, the equilibrium constant $K=1$.
