Description

By means of the Knudsen effusion method the heat of sublimation of WBr5 has been measured and the enthalpy of formation of WBr5 has been calculated. (author)

Abstract (German)

Die Sublimations‐Enthalpie von WBr 5 wurde mit Hilfe einer massenspektrometrischen Knudsen‐Effusionsmethode im Temperaturbereich von 359–417 K gemessen. Aus den Meßergebnissen wurde berechnet: ΔH° (subl. WBr 5 , 298) = 26,3 ± 0,8 Kcal/mol. Unter Verwendung der Bildungsenthalpie von festem WBr 5 (−74,5 ± 3 Kcal/mol, [4]), folgt hieraus die Bildungsenthalpie vom gasförmigen WBr 5 ΔH f ° (WBr 5 ,g, 298) = −48,2 ± 3,8 Kcal/mol.
