Russian Chemical Bulletin Aims and scope

Abstract

The dissociation pressure for the process PtCl2(s) → Pt(s) + Cl2(g) was measured by the static method with diaphragm zero-pressure gauges. The approximating equation for the temperature dependence on the dissociation pressure for the above reaction was found. The enthalpy (137.7±0.3 kJ mol−1) and entropy (163.6±0.4 J mol−1 K−1) of PtCl2(s) dissociation and enthalpies of formation and absolute entropies of platinum di- and trichlorides at 298.15 K were calculated.
