Enthalpy of formation of chromium(III) chloride

Article abstract of DOI:10.1016/0021-9614(90)90131-9

Subjecting a chromium sample (mass fraction of impurities 2 x 10^-4) to chlorination in a calorimetric bomb with a microfurance for sample heating made it possible to determine the standard molar change of energy at 298.15 K for the reaction: Cr(cubic) + 1.5Cl2(g) = CrCl3(hexagonal).The standard molar enthalpy of formation of CrCl3(hexagonal) at 298.15 K was calculated to be -(544.4 +/- 1.4) kJ.mol^-1.Here and in the paper uncertainties are given for a 95 per cent confidence interval.)
