The behavioral features of a mixture containing many species each of which participates in two competing parallel first‐order reactions may deviate significantly from those of the individual species. For example, the grouped selectivity may depend on the conversion and attain up to N ‐2 extremal values where N is the number of the reactants in the mixture. The kinetics of the grouped species depends on the composition of the feed and can be of an unconventional functional form. The use of empirical grouped kinetics may lead to unexpected pitfalls. For example, grouped rate expressions based on experiments carried out in one reactor may not be adequate for predicting the behavior in a reactor with a different residence time distribution.
