Abstract
Two approaches (discriminating (1) and isoconversional (2)) to the eva luation of Arrhenius parameters for the thermal decomposition of solid s under nonisothermal conditions are investigated and applied to both modeled and experimental data: Approach (1) allows only for the detect ion of an isokinetic relationship (IKR) but not for unambiguously esti mating its parameters and approach (2) makes it possible not only to d etect an IKR but also to determine its parameters. These may in turn b e used to obtain information about the actual reaction pathway of the thermally induced process. The thermal decomposition of tetranuclear C u(II) complexes with various ligands is used as an experimental exampl e.
