The standard massic energy change at the temperature T = 298.15 K for the reaction: GeTe(cr)+5F2(g)=GeF4(g)+TeF6(g) has been measured in a fluorine-bomb calorimeter, and from it has been derived the standard molar enthalpy of formation DfHΒ°m(GeTe, cr, 298.15 K)=-(18.224.6) kJβ’mol -1 . On the basis o
new DfHΒ°m (GeS,cr,298.15 K) obtained in Part II of this study (J. Chem. Thermodynamics 1994, 26, 727), yield several derived results for DfHΒ°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):
