The high-pressure limit of the rate constant Um,oo is readily measured. From the assumptions in the model, molecular collision theory should be adequate to predict the excitation-reaction rate constant ke, using Eq. 10.76 ...

According to the molecular collision theory of kinetics, only collisions between molecules with high enough energy can result in reaction(s). In other words, a chemical reaction occurs only when the two conditions are met (1) the molecules to take part in the reaction collide with each other and (2) the colliding molecules have a sufficiently high energy level. 

The scales involved in such a reactor should be defined in a relative manner. For a chemist, the molecule is at the start and catalyst (particle) at the end of the scales. To reveal the reaction mechanism over a catalyst particle, a sequence of network of elementary reactions" will be needed. Accordingly, on the basis of, for example, the molecular collision theory (Turns, 2000), the "global reaction" can be derived in terms of global rate coefficient and reaction order. Here, the resultant reaction mechanism is termed "global" by chemists, because the use of it for a specific problem is normally a "black box" approach, without knowing exactly the underlying networks or structures of chemical routes from reactants to products. On the other hand, for a chemical reaction engineer, the catalyst (particle) is often the start and the reactor is the end. The reaction free of inner-particle and outer-particle diffusions, that is,...

Molecular collision theory. The molecular collision theory proposes that undecomposed hydrocarbon fuel molecules directly in front of the explosion wave will be bombarded and thus activated by the highly active molecules from the explosion wave itself. Garner and Saunders 85 studied this phenomena by means of the spectra of acetylene air detonations. They explain the formation of carbon in such detonations by the decomposition of acetylene into 2C and Ha by the action of molecular collisions. The application of this theory to the mechanism of the action of antiknocks in internal combustion engine operation is not clear. 

Reinhard Schinke received his Ph.D. in physics in 1976 at the University of Kaiserslautern, Germany, working in the held of molecular collision theory. In 1980, after 1 year at the IBM research laboratory in San Jose, California, as a postdoc, he entered the department of molecular interactions at the Max-Planck Institute for Fluid Dynamics in Goettingen where he has remained since. His research switched from collisions to the area of photodissociation and more recently to unimolecular reactions. Currently he studies the recombination of ozone with particular emphasis on a dynamical explanation of the pronounced isotope effect, which has been observed both in the atmosphere and in the laboratory. Throughout his scientihc career, he has tried to understand experimental observations on the basis of accurate potential energy surfaces and exact dynamics calculations.

Since an exact quantum-mechanical description of the collisions is possible only for very simple systems, it is clear that approximate methods, combining the simplicity of classical calculations with the possibility of taking into account quantum effects, will be very useful for the molecular collision theory. A promising method of this kind is the "classical S-matrix method developed by MILLER /IO6/. It represents a quasi-classical approach which consists of passing to the classical limit of the scattering operator defined by (21.11).
