Me. Huntelaar et Ehp. Cordfunke, THE STANDARD MOLAR ENTHALPIES OF FORMATION OF BAO(G) AND SRO(G), Journal of Chemical Thermodynamics, 29(7), 1997, pp. 817-826
The standard molar enthalpies of formation of BaO(g) and SrO(g) have b
een obtained from an extensive literature assessment. Whereas the enth
alpy of formation of BaO(g) obtained from the enthalpy of sublimation
of BaO(s), is in good agreement with the dissociation energy, the valu
es for SrO(g) are less unambiguous. The values obtained are Delta(f)H(
m) degrees(298.15K) = -(112 +/- 5) kJ.mol(-1), and Delta(f)H(m) degree
s (298.15K) = (1.5 +/- 15) kJ.mol(-1) for BaO(g) and SrO(g), respectiv
ely.
