The enthalpies of solution of hydrous ytterbium chloride, APDC, o-phen·H2O, the mixture of APDC with o-phen· H2O in absolute ethanol at 298. 15 K, and the enthalpy changes of liquid- phase reaction of formation for Yb （ C5H8NS2 ）3 （ C12H8N2） at different temperatures were measured by using a RD496-Ⅲ microcalorimeter. Fundamental paconduction microcalorimeter, determining the specific heat a calculation model for capacity of solid subrameters, the activation enthalpy （ΔH≠^θ）, the activation entropy （ΔS≠^θ）, the activation free energy （ΔG≠^θ）, the apparent reaction rate constant （k）, the apparent activation energy （ E ）, the pre-exponential constant （A） and the reaction order （n）, were obtained by the combination of the thermochemical data of the reaction and kinetic equations with the data of thermokinetic experiments. The enthalpy change of complex formation from the reaction of the regents in solid phase, ΔrH≠^θ（s）, was calculated on the basis of an appropriate thermochemical cycle and other auxiliary thermodynamic data.
