Abstract :
The paper discusses the kinetic results, which the participants in the ICTAC Kinetics Project have produced from the provided isothermal and nonisothermal data on a hypothetical simulated process, as well as on the thermal decomposition of ammonium perchlorate. The majority of the participants have applied various model-free techniques that employ multiple sets of isothermal or/and nonisothermal data obtained at different temperatures or/and at different heating rates. These ‘multi-set’ methods have been very successful in detecting multi-step kinetics in the data provided. Fitting data to multi-step kinetic models has allowed the ‘true mechanism’ to be guessed for the simulated data. For the real data, the mechanistic guesses happened to be uncertain. Various ‘multi-set’ methods have allowed fairly consistent values of the Arrhenius parameters to be derived from isothermal and nonisothermal data.
