【Abstract】 The reaction enthalpy of coordination reaction of lanthanum chloride with Glycine is determined by solution calorimetry in an isoperibel reaction calorimeter. The calormetric solvent is the solution of hydrochloric acid (2 mol· L－ 1), a new thermochemical cycle is designed. According to the results, the following date: (298.2 K)=－ 4.310 kJ· mol－ 1 (La(Gly)3Cl3· 5H2O, s, 298.2 K)=－ 4222.93 kJ· mol－ 1 were obtained.更多还原
