Zel'dovich mechanism is a chemical mechanism that describes the oxidation of nitrogen and NOx formation, first proposed by the Russian physicist Yakov Borisovich Zel'dovich in 1946. The reaction mechanisms read as
NO formation
The rate of NO concentration increase is given by :\frac{d[\mathrm{NO}]}{dt}= k_{1f} [\mathrm{N}_2] [\mathrm{O}] + k_{2f} [\mathrm{N}] [\mathrm{O}_2] + k_{3f} [\mathrm{N}] [\mathrm{OH}] - k_{1b} [\mathrm{NO}] [\mathrm{N}] - k_{2b} [\mathrm{NO}] [\mathrm{O}] - k_{3b} [\mathrm{NO}] [\mathrm{H}] ==N formation==
N formation
Similarly, the rate of N concentration increase is :\frac{d[\mathrm{N}]}{dt}= k_{1f} [\mathrm{N}_2] [\mathrm{O}] - k_{2f} [\mathrm{N}] [\mathrm{O}_2] - k_{3f} [\mathrm{N}] [\mathrm{OH}] - k_{1b} [\mathrm{NO}] [\mathrm{N}] + k_{2b} [\mathrm{NO}] [\mathrm{O}] + k_{3b} [\mathrm{NO}] [\mathrm{H}] ==See also==
