Abstract
The kinetics of the reaction between oxygen atoms and cyanogen have been studied in a capacity flow reactor at temperatures between 570 and 687 °K. The concentration of CN radicals was measured by electronic absorption spectroscopy. This work confirms the previously proposed mechanism (part II). The initial step has a rate constant of k 1 = 2∙5 (± 0∙3) x 10 13 exp ( – 11000±2000/ RT ) cm 3 mole –1 s –1 . CN radicals are removed mainly by reactions (4) and (2) for which k 4 = 6∙3 (±3∙5) x 10 13 exp (–2400±700/ RT ) cm 3 mole –1 s –1 and k 2 = 4∙4 (±2∙0) x 10 12 cm 3 mole –1 s –1 . CN+O = CO+N, (4) CN+O 2 = NCO+O. (2) The rates of reaction of CN with NO and NH 3 were also measured; for CH 4 and H 2 limiting values were obtained.
