Description / Table of Contents:
Saturation Pressure of GaCl3 and InCl3The saturation pressure of GaCl3 and InCl3 was measured in a Membran Zero Manometer. The enthalpy and entropy of sublimation or evaporation were derived from the temperature functions of the partial pressure via the constants of dissoziation.
Notes:
Der Gesamtsättigungsdruck über Galliumtrichlorid und Indiumtrichlorid wurde im Membrannullmanometer gemessen. Aus den Temperaturfunktionen der Partialdrücke wurden über die Dissoziationskonstanten die Sublimations- bzw. Verdampfungsenthalpien und -entropien hergeleitet: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{l} \Delta {\rm H}^\circ {\rm (Ga}_{\rm 2} {\rm Cl}_{\rm 6} {\rm,verd,298) = 12,9} \pm {\rm 0,3 kcal/mol}\\ \Delta {\rm S}^\circ {\rm (Ga}_{\rm 2} {\rm Cl}_{\rm 6} {\rm,verd,298)\, = 28,6} \pm {\rm 0,5 cal/k} \cdot {\rm mol}\\ \Delta {\rm H}^\circ {\rm (In}_{\rm 2} {\rm Cl}_{\rm 6} {\rm,sub,298)\,\,\,\, = 44,8} \pm {\rm 0,6 kcal/mol}\\ \Delta {\rm S}^\circ {\rm (In}_{\rm 2} {\rm Cl}_{\rm 6} {\rm,sub,298)\,\,\,\, = 58,7} \pm {\rm 0,7 cal/k} \cdot {\rm mol}\\ \Delta {\rm H}^\circ {\rm (InCl}_{\rm 3} {\rm,sub,298)\quad = 38,8} \pm {\rm 0,6 kcal/mol}\\ \Delta {\rm S}^\circ {\rm (InCl}_{\rm 3} {\rm,sub,298)\quad = 49,3} \pm {\rm 0,7 cal/k} \cdot {\rm mol}\\ \end{array} $$\end{document}.
