Note:
For rather a long time numerical results in chemical kinetics could only be obtained for very simple chemical reactions, most of which were of minor practical importance. The availability of fast computers has provided new opportunities for developments in chemical kinetics. Chemical systems of practical interest are usually very complicated. They consist of a great number of different elementary chemical reactions, mostly with rate constants differi ng by many orders of magnitude, frequently with surface reaction steps and often with transport processes. The derivation of a 'true' chemical mechanism can be extremely cumbersome. Mostly this work is done by setting up 'reaction models' which are improved step by step in comparison with precise experimental data. At this early stage mathematics is involved, which may already be rather complicated. Mathematical methods such as pertubation theory, graph theory, sensitivity analysis or numerical integration are necessary for the derivation and application of optimal chemical reaction models. Most theoretical work aimed at improving the mathematical methods was done on chemical reactions which mostly were of little practical importance. Chemical engineers, who evidently know well how important the chemical models and their dynamics are for reactor design, have also to be convinced not only on the theoretical work but also on its practical applicability
