Thermodynamics. By correlating thermochemical and electrochemical data for liquid ammonia, it has been possible to estimate thermodynamic functions for a wide variety of ionic species in liquid ammonia at 25 ° C. (22,24). The heats and free energies of formation and entropies (relative to H+) for a few species are given in Table I. These values have been calculated from the data of references 6,19, 20, and 24.
