摘要:

1.As a result of the measurements described in our article it has been found that for the reaction Basolid+ Sesolid+ 2O2=BaSeO4, ΔH298=-279.2 Cal/mole and ΔF298=-249.1 Cal/mole; and for the reaction Pbsolid+ Sesolid+ 2O2=PbSeO4ΔH298== -148.7 Cal/mole and ΔF298=-120.5 Cal/mole.2.From the thermodynamic data for H2SeO4, SrSeO4, BaSeO4, PbSeO4, and Tl2SeO4the average value of the entropy of the aqueous SeO42−ion is S=5.5 ± 0.3 entropy
