Results: The results obtained from kinetic parameters were used to evaluate the thermodynamic parameters, i.e., entropy of activation (ΔS), enthalpy of activation (ΔH), and Gibbs free energy of activation (ΔG), corresponding to the activation by using previously mentioned equations. Kinetics of degradation for the synthesized complexes in solid state were studied using thermogravimetric analysis technique (TGA) in nitrogen atmosphere. result: Moreover, the results obtained from kinetic parameters were used to evaluate the thermodynamic parameters, i.e. entropy (ΔS), enthalpy (ΔH) and Gibbs free energy (ΔG) corresponding to the activation by using previously mentioned equations.
