Web1 Free energy: the Gibbs function. The Gibbs [free] energy (also known as the Gibbs function) is defined as. G = H – T S (4-1) in which S refers to the entropy of the system. Since H, T and S are all state functions, so is G. Thus for any change in state, we can write the extremely important relation. Δ G = Δ H – T ΔS (4-2) Must know this! WebGibbs Energy Difference Functions, calculated from phase equilibria in the system CaO-Al 2 O 3 -SiO 2 - (H 2 O-CO 2 ), can be used to estimate consistent ΔH 0 f , ΔG 0 f (298,1) values for aluminous minerals.
