Abstract: The standard molar reaction enthalpy of the solid-solid coordination reaction, La(NO3)3. 6H2O (s) + 4Ala(s) (Ala is Alanine) =La(NO3)3· (Ala)4·H2O(s) + 5H2O(1), has been studied by the classical solution calorimetry. The molar dissolution enthalpies of the reactants and the products in2 mol/L HCl of this solid-solid coordination reaction have been measured by using an isoperibol calorimeter. From the results and other auxiliary quantities, the standard molar formation enthalpies of [La(NO3 )3· (Ala)4· H2O, s, 298.15 K] have been determined to be[La(NO3)3·(Ala)4· H2O, s, 298. 15 K]= -3864.247 kJ/mol.

Key words: Lanthanum nitrate, Alanine, Thermochemistry, Standard molar formation enthalpy
