Gibbs free energy isothermal expansion
WebA ≡ U − T S. (22.1.1) d A = d U − T d S − S d T. If we also set T constant, we see that Equation 22.1.1 becomes. d A = d U − T d S ≤ 0 constant V and T. This means that the Helmholtz energy, A, is a decreasing quantity for spontaneous processes (regardless of isolation!) when T and V are held constant. A becomes constant once a ...
