Thermodynamic Properties of Sulfur Compounds I. Hydrogen Sulfide, Diatomic Sulfur and the Dissociation of Hydrogen Sulfide

摘要

The thermodynamic properties of H2S are calculated from the structure recently obtained by the analysis of an infrared band. — [(F0—E00)/T]*298.1= 41.174.S*298.1= 49.151. (Not including the spin contribution.) Montgomery and Kassel's calculations for S2are corrected in accordance with Badger's new interpretation of the data of Naude´ and Christy. — [(F0—E00)/T]298.1= 47.242.S0298.1= 54.417. The results are applied to the reaction H2S = H2+½S2. The energy of dissociation of H2S into normal atoms,E00, is found to be 173.8 kg cal. per mole.
