The theorem of common kinetic runs - a concept against an unorganized data overflow in reaction kinetics

Abstract

Based on the well-proven system of kinetic coordinates, derived from shape index and halfwidth of a derivative non-isothermal signal, on the activation data of the internal one-step reference reaction and on N intervals of the starting concentration of a reactant, a 3 × N matrix can be defined which fixes the kinetics occurring in a homogeneous system and is available from experimental or theoretical series. This readily available matrix, called Mechanistic Concentration Code (= MCC), was recently proven to be an ideal vehicle for data abstraction because it is nearly independent of activation data and methodical coefficients and indicates the rate-determining source processes and their molecularities. As was confirmed by DTA- and rate curves of numerous complex reactions, it enables one to get a distribution list for all two-step processes involved, revealing smallest differences in the kinetics.
