| Abstract: | The thermal decomposition of WOCI3 proceeds in the first decomposition step according to 2 WOCl3,s = WOCl2,s + WOCl4,g. The second decomposition step of WOCI3 is identical with the thermal decomposition of WOCI2, equation see “Inhaltsübersicht” The interpretation of the decomposition equilibrium of WOCl3 gives the heat of formation: ΔH°(WOCl2,s,298) = ?155(±4) kcal/Mol. The heat of formation δH° (WOCl3,s,298) = ?174,15(±0,8) kcal/Mol was determined from the solution enthalpy of WOCl3 in 2n NaOH with 1% H2O2. |
