摘要

Potentials for the thermocell (298.15 exp 0 K) Ag-AgCl/NaCl/AgCl-Ag(T exp 0 K) have been determined for NaCl concentrations ranging from 0.005 to 0.5 mol/Kg and for temperatures as high as 548.15 exp 0 K. Thermodynamic analysis of the cell has permitted evaluation of the initial state thermal liquid junction potentials ( delta phi/sub TLJP/) over the same range of conditions, and it was found that delta phi/sub TLJP/ increases in an approximately parabolic manner with delta T(=T-298.15 exp 0 K). The entropy of transport function t/sub +/S*/sub NA/sup +// - t /sub -/S*/sub Cl/sup -// has also been calculated. (ERA citation 09:012102)
