Reaction Kinetics & Chemical Reaction Models

General Features of Reaction Mechanisms

There are fundamental features in most reaction mechanisms occurring in the gas phase that can be used to assemble such mechanisms. The most important one is the role played by free radicals in the decomposition of any reactant. A very simple example found in freshman chemistry books is the formation of hydrogen iodide starting from hydrogen and iodine (Chang, 1994). The proposed mechanism is a two-step mechanism,

Reaction Kinetics & Chemical Reaction Models

The fundamentals of chemical reaction kinetics will be presented with the purpose of building, starting with elementary reactions,
complex mechanisms. These mechanisms consisting of many elementary reactions can be used with existing software (discussed later) to make predictions on the performance of chemical reactors with special consideration to the formation of trace species. The focus will be on homogeneous processes taking place in the gas phase. The majority of the material presented in this manuscript is based on the author’s own research (Gargurevich, 1997).
