Excess Gibbs Energies

The results of the determination of the thermodynamic properties for ternary systems Cr.Co.Me (Me = Mo, Al) using a new general solution model for the predictions are presented in this work. For five sections (with mole ratio Co :Me = 2:8, 4:6, 5:5, 6:4, 8:2) investigated in each ternary system at temperature of 2000 K, integral molar excess Gibbs energies and partial molar thermodynamic properties of chromium were calculated.

Abstract The Knudsen effusion technique combined with mass spectrometry has been applied to determine thermodynamic activities and excess Gibbs energies for the liquid Cu-Si System. The system shows a tendency for segregation over the entire composition range. Special features in the partial and integral properties could be interpreted by means of two models.

We have estimated the degree of polarizability of a polarized oil-water interface used as a working interface and that of the nonpolarizability of a nonpolarized interface used as a reference oil-water interface from the numerical calculation of dc and ac current vs potential behavior at both interfaces. Theoretical equations of dc and ac currents for simultaneous cation and anion transfer of supporting electrolytes have been derived for the planar stationary interface for reversible and quasi-reversible cases. In the derivation, the migration effect and the coupling of the cation and anion transfer have been incorporated. The transfer of ions constituting a supporting electrolyte contributes to the total admittance of the interface even in the region where the interface may be considered as polarized in dc sense, as pointed out first by Samec et al. (J. Electroanal. Chem. 126, 121 (1981)). Moreover, the reference oil-water interface is not ideally reversible, so that the contribution from this interface to the measured admittance cannot be negligible, unless the area of the reference oil-water interface is much larger than that of the working oil-water interface. The effect of non-ideality of the reference oil-water interface on the determination of double layer capacitances and kinetic parameters of charge transfer at the working oil-water interface has been estimated.
