High pressure-temperature phase equilibrium
WebApr 12, 2024 · At high pressures, a substance may have additional triple points for two solid phases and the liquid, or for three solid phases. This is illustrated by the pressure–temperature phase diagram of H 2 O in Fig. 8.4, which extends to pressures up … WebWhen both temperature and pressure are held constant, and the number of particles is expressed in moles, the chemical potential is the partial molar Gibbs free energy. [1] [2] At chemical equilibrium or in phase equilibrium , the total sum of the product of chemical potentials and stoichiometric coefficients is zero, as the free energy is at a ...
