Thermochemistry of (germanium + sulfur): III. Massic energies of combustion in fluorine and the derived standard molar enthalpies of formation of crystalline and vitreous germanium(IV) disulfide GeS2at the temperatureT= 298.15 K. Standard molar enthalpy of the transition GeS2(cr) = GeS2(vit) atT= 298.15 K. Critical assessment of thermodynamic quantities for the high-temperature reaction: GeS2(cr) = GeS(g) + 12S2(g)

new DfH°m (GeS,cr,298.15 K) obtained in Part II of this study (J. Chem. Thermodynamics 1994, 26, 727), yield several derived results for DfH°m(GeS2,cr,298.15 K) that are in reasonable agreement with the calorimetric determinations. The standard molar enthalpy of the transition: GeS2(vit) = GeS2(cr):
