Drowart and published by . This book was released on 1964 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The composition of the vapor in equilibrium with lead oxide (yellow rhombic form) in the temperature interval 1000-1150K was determined mass spectrometrically. The predominant species are PbO, Pb2O2, Pb3O3 and Pb4O4. From the partial PbO pressure measured here and that based on a reinterpretation of the literature data, when taking the presence of the polymers into account, the dissociation energy of the molecule PbO= 88.4=1.4 kcal/mole. The standard enthalpy at 25C of the reactions, Pb2O2(g) 2 PbO(g), Pb3O3(g) 3PbO(g), Pb4O4(g) 4 PbO(g), is 63.4=4, 126.4=6.0 and 202.0=10.0 kcal/mole respectively. (Author).

COLIN and published by . This book was released on 1964 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a mass spectrometric investigation of the vapor in equilibrium with solid SnSe and solid SnTe, a number of reaction enthalpies were measured and from known thermochemical data, the following thermochemical values were calculated: enathapy of formation at 298 degrees of SnSe and SnTe; dissociation energy of SnSe and SnTe; enthalpy of dimerization at 298 degrees of SnSe, SnTe, and SnTe2. The dissociation energies were compared to the available spectroscopic data.

Drowart and published by . This book was released on 1964 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A mass spectrometric study of the vaporization of the compounds GeO2 (hex) and GeO(am) and of the mixture GeO2(hex) + Ge(c) made it possible to establish their mode of vaporization: (I) GeO2(hex) - GeO(g) + I/2O2; (II) n GeO(am) - (GeO)n(g) (n=1, 2, 3); (III) n/2 GeO2(hex) + n/2 Ge(c) - (GeO)n(g) (n = 1, 2, 3). The enthalpies of vaporization at 298K are: (I) = 121.2=1.6 kcal/mole; (II, n = 1) = 53.4=1.0 kcal/mole; (III, n = 1) = 58.2=1.0 kcal/mole. The polymerization energies at 298K are: (GeO-GeO) = 44.7=3.0 kcal/mole; (GeO-GeO-GeO)= 88.5=5.0 kcal/mole. Total pressures given in the literatuure were reinterpreted taking the presence of the polymers into account. The heat of formation of the metastable compound GeO(am) obtained is -59.6 = 0.7 kcal/mole. The dissociation energy of the gaseous molecule GeO is 157.4=1.5 kcal/mole. (Author).
