Conclusion A semiempirical approach, which permits hot-atom reactions to be melded with nonhot-atom reactions in a kinetic scheme, is outlined and appears to work unusually well for the two cases explored. The simulated results were generally in good agreement with the experimental findings of Martin and Willard. The results pertaining to the percentage of successful hot hydrogen reactions with methane for either the (DBr+ CHI) or the (HBr+ ...
