Nonisothermal Molten Silver Chloride Cells
1962
The determination of the emf of the nonisothermal cells Ag/AgCI(1)/Ag and Ch/AgC1 (1)/CI.~ is used to estimate the magnitude of the transport entropy terms in the general equation for thermogalvanic potentials. The emf's were determined over the temperature range 500~176 with temperature differentials ranging from 40 ~ to 400~ The limits of accuracy of the measurement are established by reference to accurately known reversible thermodynamic quantities; the irreversible quantities are demonstrated to be small, but not negligible as they were reported to be in solid electrolyte cells; and the Seebeck coefficient's independence of the transport numbers in the system was experimentally confirmed.
