0.1 Minimum Principles and Thermodynamic Potentials
... The minimum principle for G then states that for all states at a fixed T and P , the equilibrium state is that for which G is a minimum. The proof is very similar to that for A: the second law states that ∆Q ≤ T ∆S or 0 ≥ T ∆S + ∆U + P ∆V , if P is held fixed. But dG = dU − T dS + P dV , so dG ≤ 0 i ...
