Thermal Decomposition Kinetics of Thorium(IV) and Dioxouranium(VI) Complexes

Department of Chemistry, Government Post-Graduate College, Morena-476 001

Thermal decomposition kinetics studies of thermal reactions are useful in studying parameters like free energy change (ΔG*), enthalpy change (ΔH*), activation energy (E*) and ultimately the entropy change (ΔS*) and pre-exponential factor (A) or frequency factor (Z). This concept was f"u-st proposed somewhere In 1928. Since then so many methods and equations have been put forward for studying thermal decomposition kinetics of the reaction Present report discusses some aspects of non-isothermal kinetic studies of some thorium(IV) and dioxouranium(VI) complexes with various pyrazolones, amine N-oxides and aromatic Schlff bases.
