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 ...
WebJul 12, 2024 · The chemical potential of a particular component is the Gibbs free energy per mole of that component in the homogeneous solution. For example, a substance can be a binary solution A xAB xB of composition x A and x B, with x A + x B = 1, μ = μ Ax A + μ Bx B.
