WebAbstract Gibbs–Duhem equation is one of the fundamental equations in thermodynamics, which describes the relation among changes in temperature, pressure and chemical potential. Thermodynamic system can be affected by external ﬁeld, and this effect should be revealed by thermodynamic equations. Based on energy WebThe entropy change is Δ S = 40.65/ 373 = 0.109 kilojoules per mole∙K, (21) representing the higher degree of disorder when water evaporates and turns to steam. The Gibbs free energy change is Δ G = Δ H − T Δ S. In this case the Gibbs free energy change is zero because the water and steam are in equilibrium, and no useful work can be ...
