Abstract

A method of calculating the Arrhenius parameters has been proposed, based on an evaluation of the coordinates of intersection of greatly extended confidence regions determined in solving the inverse kinetic problem. The validity of this method is illustrated by comparison of the Arrhenius parameters found from non-isothermal and isothermal data reported by other investigators.

Zusammenfassung

Es wird eine Methode zur Berechnung der Arrhenius-Parameter vorgeschlagen, die auf der Auswertung der durch Lösung des inversen kinetischen Problems bestimmten Koordinatenabschnitte mit weit ausgedehnten Konfidenzbereich beruhen. Die Anwendbarkeit dieser Methode wird an Hand eines Vergleichs der Arrhenius-Parameter demonstriert, die aus von anderen Autoren mitgeteilten nicht-isothermen und isothermen Daten erhalten wurden.
