TL;DR: In this article, the energy dependence of chemical and ionic reactions is examined and a new model is developed for the calculation of reaction probability and postreaction energy disposal for exchange reactions.
Abstract: In this article the energy dependence of chemical and ionic reactions is examined and a new model is developed for the calculation of reaction probability and postreaction energy disposal for exchange reactions. The new model is based on the principles of the maximum entropy method. For the exchange reactions the reaction probability is based on either the translational or the vibrational energy of the reagents as appropriate, whereas for dissociation the vibrational energy is used as the controlling factor. The new method is compared with other methods used for direct simulation Monte Carlo calculations. Examples of flowfield solutions are presented and the differences between the results of the new method, those using Bird's method, and continuum solvers are discussed and evaluated.
