Quantitative Relationship between the Rate Constant of Quadratic Chain Branching and the Rate of Nonthermal Flame Propagation

Abstract

The pattern of the quantitative relationship between the rate constant of the quadratic branching of reaction chains and the rate of nonthermal flame propagation is determined by the example of the chain decomposition of nitrogen trichloride. It is shown that, due to this functional relationship, the values of the rate constants for the NCl₂ + NCl₂ = N₂ + 4Cl reaction determined by the stationary rate of the decay of the flame of the nitrogen chloride and, independently, by the spectroscopic kinetic study of NCl₂ radical consumption are almost the same.
