Abstrakt: Electrode potential measurements for the title cell are presented from which thermodynamic parameters are obtained. The E&z.ccsh; values are lower than those of the same cell with pure electrolyte which results from an increase in the entropy term. There is also a decrease in the α–β transition temperature, which is ascribed to a decrease in the formation energy of the Frenkel defects which in turn is associated with the entropic change.
