Kinectics of Thermal Degradation of Lanthanum Complexes

Abstract

The kinetics and mechanism of the thermal decomposition of naphthoate complexes of lanthanum with hydrazine base have been studied by Thermal analysis techniques. The kinetic parameters for the decomposition stages (stages I and II) were calculated using the Coats Redfern equation. It is observed that there is no regular variation in the values of the kinetic parameters of decomposition of the complexes. Entropy of activation found to be positive in most of the complexes indicate the activated complexes have a less ordered structure than the reactant.
