Using the thermal decomposition of [Co(NH3)6]2(C2O4)3·4H2O as a basis, the paper presents results which show how computed values of kinetic parameters are influenced by experimental
conditions (ambient atmosphere, sample mass, linear heating rate) when using the non-isothermal methods and the Coats-Redfern
(CR) modified equation. It also illustrates the influence of the experimental methods i.e. non-isothermal and isothermal (conventional)
methods and also a quasiisothermal-isobaric one which can be recognised as equivalent to Constant Rate Thermal Analysis (CRTA).
The results obtained have confirmed the significant influence of the experimental parameters as well as that of the experimental
method used on the estimated values of kinetic parameters. The correlation between activation energy (E) and sample mass (m) or heating rate (β) is generally of a linear nature:E=a+bx
