THE DISSOCIATION AND RECOMBINATION OF NITROGEN: A COMPARISON BETWEEN THEORY AND EXPERIMENT,

Abstract

The phase-space theory of reaction rates, as developed by Keck, which incorporates the corrections due to nonequilibrium vibrational state populations, is used to calculate the overall recombination and dissociation rate coefficients of nitrogen in a heat bath of argon atoms. Substantial quantitative agreement is obtained between the theoretical predictions and the low temperature (90K - 611K) 'discharge-flow-tube' measurements of the recombination rate coefficient and the high temperature (8000K - 15000K) 'shock-tube' measurements of the dissociation rate coefficient. The working relationships required for applying the modified phase-space theory to predict the dissociation and recombination rate coefficients of other diatomic molecules in the presence of weakly attracting collision partners, such as argon atoms, are summarized.
