Popis: The kinetic and thermodynamic parameters such as reaction order, activation energy, enthalpy, free energy and entropy change related to the thermal decomposition of Co(II), Ni(II) and Cu(II) hydrazone complexes of 4-benzamido-1-(4-actylpyridine)-3-thiosemicarbazone (BACPT) and 4-benzamido-1-(pyridine -3-aldehye)-3-thiosemicarb-azone (BAPT) were evaluated from differential thermal analysis (DTA) curves using Thomas-Clarke's method. The thermal stability of these complexes are discussed in relation to the nature ofthe metal ion and ofthe ligand present. A suitable mechanism for the thermal decomposition process of the complexes based on the data of the thermogravimetric analysis (TGA) was suggested.
