C LOG C CONTRIBUTION TO THE ELECTROLYTE CONDUCTANCE AND ONSAGER RECIPROCAL RELATION

The differential equations and the boundary conditions for the nonequilibrium binary distribution function of an unsymmetrical binary electrolyte are derived from the Ebeling-Falkenhagen continuity equation. The connection between the Onsager reciprocal relation and the binary distribution functions is shown. Further, Feistel's result for the c log c contribution to the conductance is extended to unsymmetrical binary electrolytes. The reason for the difference between Feistel's and Chen's c log c term is explained, and the significance of Onsager's reciprocal relation for the calculation of c log c and higher-concentration contributions of the conductance is discussed. © 1979 Plenum Publishing Corporation.
