Calorimetric Determination of the Enthalpy of Formation of SeBr4 and SeOBr2It was determined the enthalpy of solution of SeO2, SeBr4, and SeOBr2 in 1 N HBr and derived the enthalpies of formation. The following data basing on the enthalpy of formation for SeO2 were obtained \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{*{20}c} {\Delta {\rm H}_{\rm B}^ \circ {\rm }({\rm SeBr}_{\rm 4},{\rm f, 298)} = - 69,7 \pm 6.6{\rm kJ mol}^{ - 1} {\rm and}} \hfill \\ {\Delta {\rm H}_{\rm B}^ \circ {\rm }({\rm SeOBr}_{\rm 2},{\rm f, 298)} = - 140.0 \pm 3.3{\rm kJ mol}^{ - 1} } \hfill \\ \end{array} $$\end{document}.
Notes:
Die Lösungswärmen von SeO2, SeBr4 und SeOBr2 wurden in 1 N HBr bestimmt und daraus die Bildungsenthalpien hergeleitet. Auf der Basis der Bildungsenthalpie des SeO2 erhält man: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{*{20}c} {\Delta {\rm H}_{\rm B}^ \circ ({\rm SeBr}_{\rm 4},{\rm f, 298)} = - 69,7 \pm 6,6{\rm kJ mol}^{ - 1} {\rm und}} \hfill \\ {\Delta {\rm H}_{\rm B}^ \circ ({\rm SeOBr}_{\rm 2},{\rm f, 298)} = - 140,0 \pm 3,3{\rm kJ mol}^{ - 1} } \hfill \\ \end{array} $$\end{document}.
