Abstract :
The dynamic thermogravimetric analysis (TGA) of chloropentaminecobalt(III)chloride (CPCC), nitropentanaminecobalt(III)chloride (NPCC), and carbanatotetraminecobalt(III)chloride (CTCC) were carried out in absence and presence of metallic zinc under static air atmosphere. The various thermodynamic and kinetic parameters associated with the observed steps in the decomposition and reduction processes were calculated by fitting the observed weight losses to different expressions given by Horowitz and Metzer (H.M.), Coats and Redfern (C.R.), and Reich and Stivala (R.S.).The dynamic TGA data indicates the lowering of decomposition temperature, increase in the rate of decomposition, and the formation of cobalt metal as one of the decomposition products, in all three complexes. Moreover, the dynamic TGA data indicates an order of 1 for the decomposition and reduction processes suggesting that both processes follow approximately the first order kinetics in all three complexes.
