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 ...

Chemical potential and Gibbs free energy
In thermodynamics, the Gibbs free energy (or Gibbs energy as the recommended name; symbol ) is a thermodynamic potential that can be used to calculate the maximum amount of non-volume expansion work that may be performed by a thermodynamically closed system at constant temperature and pressure. It also provides a necessary condition for processes such as chemic… Josiah Willard Gibbs was an American scientist who made significant theoretical contributions to physics, chemistry, and mathematics.
