WebThe change in Gibbs free energy (ΔG) for a system depends upon the change in enthalpy (ΔH) and the change in entropy (ΔS) according to the following equation: ΔG = ΔH - TΔS. ΔGo = ΔHo - TΔSo. The relationship holds true under standard conditions or under non-standard conditions. We can take away a few generalizations regarding when a ...
