“…The equilibrium of the reaction AgeS(s) + H~(g) : 2Ag(s) + H~S(g) [11] has been investigated by various authors, most recently by Rosenqvist (27) between 490 ~ and 900~ AF ~ values for reaction [11] extrapolated to 200 ~ 400~ from Rosenqvist's data agree within _+0.2 kcal with values calculated from standard molar free energies of formation of Ages according to Table VII and values for H~S recommended by Rossini, et al (28) and Kelley (29). …”

Electromotive force measurements on galvanic cells involving solid electrolytes have been made in order to obtain the standard molar free energy of formation of CoO, NiO, Cu~O, AgeS, Ag~Se, PbS, and several phases of the system Ag-Te at elevated temperatures.Haber and Tolloczko (1), Katayama (2), Reinhold (3, 4), Treadwell, Ammann, and Zfirrer (5), Croatto and Bruno (6), Rose, Davis, and Ellingham (7), Sator (8), and others have shown that emf measurements on galvanic cells involving solid electrolytes may yield valuable thermodynamic data. The following investigations have been made in order to show new potentialities of emf measurements on galvanic cells involving solid electrolytes for the determination of the standard molar free energy of formation of oxides, sulfides, selenides, and tellurides at elevated temperatures.

The reaction of hydrogen atoms, produced by electric discharge, with vinyl chloride vapor has been studied at four widely different temperatures. Since the maximum yields of HCl at both 328 and 494 °C exceeded the flow rates of atomic hydrogen, the reaction was observed to have limited chain characteristics. The products were hydrogen chloride, ethylene, methane, and ethane. The specific reaction rate for HCl production was found to be about [Formula: see text] and that for production of ethylene plus ethane was found to be about [Formula: see text].

“…1 for the ammines of manganese(I1) sulphate, it is apparent that all the ammonia ligands in the heat of solution samples have been replaced by water molecules or chloride ions, and therefore it is necessary to subtract the heat of neutralization of ammonia from the heat of solution of every sample except the anhydrous salt. The quantity to be subtracted, 7.10 cal/l% ammonia content, is obtained from thermochemical data (8) for the equation It is probably due to this that no attempt has been made to measure ligand field splitting energies spectroscopically for the hexaammines of maganese(I1) and iron(II), since the hexaammines (or any lower ammine) do not exist in aqueous solution. It is, of course, impossible to measure the ligand field splitting energies for zinc(I1) complexes spectroscopically since all the 3d-orbitals are filled so that no absorption spectra due to the d-d transitions could be observed.…”

Various lower ammines and high-energy modifications of lower ammines of the sulphates of Mn(II), Fe(II), and Zn(II) have been prepared and their heats of solution have been measured. For each of these ammine systems, the maximum difference in heat of solution, expressed in kcal/mol of heptaammine, has been found to be of the right order of magnitude to be regarded as the ligand field splitting energy for the hexaammine complex of the metal ion.
