Determination of the Enthalpy of Formation of SmOCl by Solution Calorimetry The enthalpy of formation of SmOCl (ΔH B ° (SmOCl f , 298) = —239.9 ± 0.5 kcal/mol) was determined from the heat of solution of SmOCl (ΔH L (SmOCl f 298) = —31.24 ± 0.15 kcal/mol) on the base of the enthalpies of formation of Sm 2 O 3 and SmCl 3 and their heats of solution in 4n HCl.
