The activation energy of the thermal decomposition of finely ground LaC2O4Br was determined according to the method of Ozawa asEa=203.83 kJ mol−1. As compared to the value for the parent oxalate La2(C2O4)3Ea=130 kJ/mol), this value is higher by about 70 kJ/mol, which is consistent with the increased interaction between the metal and oxalate ions. The substitution of Br by Cl does not affect the decomposition kinetics profoundly.
