| Abstract: | The content of saturated vapors above europium dibromide and Eu-EuBr2, Eu-Ba-BaBr2, EuBr2-LaBr3 systems is investigated by means of high-temperature mass-spectrometry in the electron ionization and thermoionic emission regimes. On the basis of the measured equilibrium constants for reactions with participation of molecules and negative ions, the enthalpies of formation ??fH298° (kJ/mol) are determined using the method of the third law of thermodynamics: ?59 ± 13 (EuBr), ?349 ± 19 (EuBr2), and ?861 ± 24 (EuBr 3 ? ). |
