Recombination of carbon monoxide and atomic oxygen at high temperatures.

摘要: Recombination of carbon monoxide and atomic oxygen was studied in the expansion wave a single-pulse shock tube at temperatures from 2800° to 3600°K, pressures 8.8 22.6 atm. This technique found be simple valuable means studying high-temperature recombinations. Measurements incident velocity pressure reflected zone, combined with relatively calculations chemical equilibria, sufficed determine quite accurately initial conditions before expansion. Rate constants were derived measurements intensity flame-band emission, which is proportional product concentrations. A three-body mechanism recombination assumed, results consistent this assumption. The lower-limit rate for had an average value 2×10 13 cm 6 mole −2 sec −1 estimated upper limit about 1×10 14 over range experiments. result equilibrium dissociation rates dioxide measured behind waves. present work lower than expected on basis previous direct made temperatures. It suggested that surface water catalysis may have produce these discrepancies.
