Abstract: The coordination reaction of lanthanum pcrchloratc with 18-crown-6 in acctonitrilc was determined at 298.15K by calorimetric titration. The enthalpy of coordination reaction and stability constant of coordination compound were calculated by using computer. Furthermore, the values of free energy and entropy of coordination reaction were obtained. The result show that the enthalpy change is exothermic.
