WebNov 17, 2016 · The Gibbs Free Energy, is the Legendre Transform G ≡ U [ T, p] so, G = U + p V − T S First, let's get the equation of state S ( T, V, N) from the the fundamental relation. We eliminate U using U = c N R T S ( T, V, N) = N S 0 + N R ln [ ( T T 0) c ( V V 0) ( N 0 N)]. Also, for an Ideal Gas, p = N R T V WebSep 2, 2016 · ChemTexts. This short paper deals with the close relation of the Gibbs–Helmholtz (G–H) equation to entropy. It is shown that the G–H equation is readily derived from the entropy equivalent of the Gibbs function, the Massieu function. This derivation is also compared to another simple and straightforward derivation which …
