Mean free energy

When the Fermi level of electrons in the solid is the same as the mean free energy AF for the redox reaction in die solution,... 

The premise of the HK method is that the pressure at which pore filling occurs may be obtained from the mean free energy change of the adsorbate molecule as it is transferred from the bulk gas phase to the adsorbed phase, through the equation... 

The simple theory is completely characterized by two dimensionless parameters Pe and Vj /e. p is (kBT), in which T is absolute temperature and fcg is the Boltzmann constant. Vp is defined as the backbone delocalized-electron contribution to the attractive polymer-solvent dispersion interaction per site when the polymer is in the fully ordered al -trans (rod) conformation. The ratio Vj /e (in which e is the mean free energy of defect formation), referred to as the coupling constant, is both a polymer- and a solvent-dependent quantity and plays a special role in the theory. 

Dependence on Substituent Structure. The molecular nature of the side groups has two effects (I) it influences and, presumably, largely determines the mean free energy of defect formation (e) via steric effects on the enthalpy associated with defect creation and possible entropic contri-... 

In the original HK method [19], an analytic pore filling correlation is obtained by calculating the mean free energy change of adsorption that occurs when an adsorbate molecule is transferred from the bulk vapor phase to the condensed phase in a sht pore of width H... 

In Eq. (31), Pq is the saturation pressure and Pc is the pore condensation pressure. The assumed exponential dependence of the condensation pressure on the adsorption free energy change is similar in basis to the Polanyi potential theory [101] and the Frenkel-Halsey-Hill (FHH) theory [102-104]. In the HK method, the mean free energy change due to adsorption is calculated... 

The question of atom location in boundary sites requires special consideration. The noncoincident sites form some connected sets, i.e., the complexes of noncoincident sites lying in boundary layers. Let us denote the complex that comprises N noncoincident sites with m atoms in them by CN(m). To find the most probable number of atoms arranged in the complex, we introduce the mean free energy of the complex... 

The terms exothermic and endothermic really refer to the enthalpy change, A//°, which may or may not be in the same direction as the free energy change, A G°, which involves entropy AS°, as well as enthalpy, AH". If we really mean free energy AG°, the proper terms are exergonic and endergonic.
