Gibbs free energy definition thermodynamics
WebGibbs free energy (G) is a state function defined with regard to system quantities only and may be used to predict the spontaneity of a process. ... Recalling the definition of pressure-volume work from the chapter on thermochemistry, note that no work has been done because the pressure in a vacuum is zero. ... The first law of thermodynamics ... WebThe 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 …
