Abstract

A new formal kinetics methodology suitable for the situation in which transformations take placesimultaneously or sequentially is presented. Based on the distinction between theoretical andexperimental quantities and with the help of the superposition principle general relationshipswere obtained to deal with simultaneous and sequential reactions. The equations presented hereare able to deal with position dependent quantities and there is no need to rely on extendedvolume. They are suitable both for model building, i. e. obtaining expressions for simultaneousor sequential reactions from models of the kinetics of each reaction in isolation as well as forextracting theoretical information from the experimentally measured quantities.
