Mixing mean molar function

In addition, the mean molar functions of mixing y = Y n, are derived from the above thermodynamic relations ... 

Figure 4 (a) Volume increments of phosphorus atoms (in cm mol ) with formal charges (P) and (M). The solid lines represent the functions Vp( (P), (M)) corresponding to equation (1). The broken lines connect volumes for cations with mixed valencies and extreme volumes, respectively, (b) Volume increment of P (in cm mol ) with molar ratio in semimetallic compounds. Mean values of sequences of compounds are given by large dots, the compounds FerP and ReePn are marked by small dots. The volumes of the various P modifications are given by open squares... 

Aoki and Chen examined the statistical thermodynamics of polynuclear linear complexes with mixed-valence states by means of the theory of correlated walk. Expressions for the equilibrium electrode potential of linear V-nuclear complexes with homoredox centers were derived as a function of the molar fraction of the oxidized moiety, the nearest-neighbor interactions and N. Under conditions of large interaction energy, two-, three- and four-nuclear complexes were predicted to have two, three, and four voltammetric peaks, respectively. For odd number of A> 3, only three peaks are predicted while for even number N>4, only four peaks are predicted. In cases where 00, the number of peaks reduces to two. 

Fm is the metal molar volume, which accounts for the steric effects at the interface, and C is a constant fitted to experimental values. This model takes care of the metal-oxygen and the metal-cation pair interactions through the quantities AHq(M) and AH y Neglecting the entropy variations, a partial mixing enthalpy AH Q may be written as a function of the AA, BB and AB pair interactions eAA. and 6ab and as a function of the mean coordination number Z of an atom A dissolved in B, in the following way ...
