Abstract:

Rate constants at 200 degree intervals from 1000 to 4000 K for tetra-atomic reactions of combustion products in nozzles were computed for triatomic-monatomic and diatomic-diatomic systems. The combustion products included CH2, NH2, HCO, HCN, NaOh, CH, NH, OH, H2, HC1, HF, C, H, O, N, C1, F, and A1. Summarized results are presented for the temperature range midpoint, 2500 K. The modified bond-energy, bond-order rate constant calculation procedure of Johnston and Parr was used in combination with the tetra-atomic partition functions of Pitzer, Herschbach, Johnston, et al. For the three tetra-atomic reacting systems on which experimental rate measurements have been made, the computed high-temperature rate constants are in good agreement with the experimental results.
