The numerical values of the logarithm of the infinite dilution activity coefficient, In gamma(infinity)(1), and excess partial molar excess enthalpy at infinite dilution, H-1(E,infinity), calculated by Zhang and coworkers are not thermodynamically consistent with each other. The calculated values do not obey the standard thermodynamic relationship that the variation in In gamma(infinity)(1) with 1/T must be equal H-1(E,infinity) divided by the universal gas constant.
