Equilibria between Platinum and Chlorine within the Temperature Range from 973 to 1373 K. The Molecules PtCl2 and PtCl3 and their Thermodynamic DataThe formation of the gaseous chlorides PtCl2 and PtCl3 by reaction of Pt or Pt/Rh with Cl2 has been investigated by equilibrium measurements by means of the flow method. Results are for Pt + Cl2 = PtCl2.g, ΔH°(298) = 26.4 kcal, ΔS°(298) = 5.4 cl and for Pt + 1.5 Cl2 = PtCl3.g, ΔH°(298) = 10.5 kcal, ΔS°(298) = - 9.4 cl.From estimated molecular-constant data the standard entropy values S°(298) (cl) have been calculated: PtCl2,g (70.3); PtCl3,g (80.5); PtCl4,g(88.9).
Notes:
Die Reaktion von Pt und Pt/Rh mit Cl2 unter Bildung gasförmiger Chloride wurde mit der Mitführungsmethode untersucht. Danach gilt für Pt + Cl2 = PtCl2,g ΔH°(298) = 26,4 kcal, ΔS°(298) = 5,4 cl und für Pt + 1,5 Cl2 = PtCl3,g, ΔH°(298) = 10,5 kcal, ΔS°(298) = -9,4 cl.Die aus (geschätzten) Molekülkonstanten berechneten Normalentropien S°(298) (cl) betragen: PtCl2,g (70,3); PtCl3,g (80,5) PtCl4,g (88,9).
