    Description / Table of Contents: Investigations on the Barogram and Melting Diagram of the Systems BiI3—HgI2 and BiI3—I2The barograms of the systems BiI3—HgI2 and BiI3—I2 are determined by total pressure measurements in a membrane manometer. The melting diagrams follow from DTA measurements and the barogram. Both systems are eutectic with eutectica at 1.5 mol% BiI3 and 110°C for BiI3—I2 and 9 mol% BiI3 and 243°C for BiI3—HgI2.
    Notes: Die Zustandsbarogramme der Systeme BiI3—HgI2 und BiI3—I2 wurden durch Druckmessungen im Membrannullmanometer ermittelt. Die Schmelzdiagramme wurden aus DTA-Messungen und den Barogrammen aufgestellt. Beide Systeme sind einfach eutektisch mit Eutektika bei 1,5 Mol-% BiI3 und 110°C für BiI3—I2 und 9 Mol-% BiI3 und 243°C für BiI3—HgI2.

    Description / Table of Contents: Investigations on the Decomposition Equilibrium BiI3 ⇌ BiI + I2 and Transport Equilibrium 2Bi + BiI3 ⇌ 3BiIWe determined the decomposition equilibrium (1) and the transport equilibrium (2) by a membranezeromanometer and by CTR experiments. The enthalpy of formation for BiI was concluded from the equilibrium constants. With the standard entropy \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm S}^{\rm 0} ({\rm BiI, g, 298}) = 65.8 \pm 0.2\,{\rm cal/K} \cdot {\rm mol} $$\end{document} follow the values \documentclass{article}\pagestyle{empty}\begin{document}$$ \Delta {\rm H}_{\rm f}^0 ({\rm BiI, g, 298}) = 20.1 \pm 4\,{\rm kcal/mol} $$\end{document} from the first, and \documentclass{article}\pagestyle{empty}\begin{document}$$ \Delta {\rm H}_{\rm f}^0({\rm BiI, g, 298}) = 22.0 \pm 2\,{\rm kcal/mol} $$\end{document} from the second equation, by both methods.
    Notes: Das Zersetzungsgleichgewicht BiIl3, g = BiI, g + I2, g (1) und das Transportgleichgewicht 2Bi, fl + BiI3, g = 3BiI, g (2) wurden im Membrannullmanometer gemessen und letzteres auch durch chemische Transportreaktionen ermittelt. Aus den Gleichgewichtskonstanten wurde die Bildungsenthalpie des BiI, g hergeleitet. Man erhält mit der Standardentropie \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm S}^{\rm 0} ({\rm BiI, g, 298}) = 65,8 \pm 0,2\,{\rm cal/K} \cdot {\rm mol} $$\end{document} aus ersterem Gleichgewicht \documentclass{article}\pagestyle{empty}\begin{document}$$ \Delta {\rm H}_{\rm B}^0 ({\rm BiI, g, 298}) = 20,1 \pm 4\,{\rm kcal/mol,} $$\end{document} und aus letzterem nach beiden Herleitungen \documentclass{article}\pagestyle{empty}\begin{document}$$ \Delta {\rm H}_{\rm B}^0 = 22,0 \pm 2\,{\rm kcal/mol}{\rm .} $$\end{document}.
