摘要
Based on thermoelectrochemical equation for an electrode reaction, the entropy change of it can be obtained by the thermoelectrochemical technology(TECT). The entropy changes of Fe(CN)-36/Fe(CN)-46,H+/H2(P0), Cu+2/Cu and Zn+2/Zn electrode reaction systems and the dilute enthalpies of the H+, Cu2+ and Zn2+ ions under the ion concentrations studied have been determined by a specially designed thermoelectrochemical equipment. The enthalpy change and entropy change for the five systems at unlimitedly diluted concentrations agree well with the literature.
