The recombination fo hydrogen atoms with nitric oxide at high temepratures

摘要

The rate cnstant for the H+NO+N_2 reaction (Rl,N_2) has been determined in the temeprature range 1000-1170 K from flow-reactor experiments on the CO/O_2/H_2O/N_2 system perturbed with different amounts of NO.The initiation temeprature of this systme is highly sensitive to reaction Rl,which is the rate-controlling step in the nitric oxide catalyzed removal of hydrogen atoms.Based on the flow-reactor results and hte limiteed amount of dat areportee in Literature,a rate ocnstant for the H+NO+N_2 reaction of 4.0x10~20T~-1.75 cm~6/(mol~2s) was determined.
