Zel'dovich mechanism

Zel'dovich mechanism is a chemical mechanism which describes the oxidation of nitrogen and NOx formation, first proposed by the Russian scientists Yakov Borisovich Zel'dovich, David A. Frank-Kamenetskii and P.Ya. Sadovnikov in 1947.^[1]^[2]^[3] The reaction mechanisms read as

{\ce {{N2}+O->[k_{1}]{NO}+{N}}}

{\ce {{N}+O2->[k_{2}]{NO}+{O}}}

where $k_{1}$ and $k_{2}$ are the reaction rate constants in Arrhenius law. The overall global reaction is given by

{\ce {{N2}+{O2}->[k]2NO}}

The overall reaction rate is mostly governed by first equation since the second equation is much faster than the first equation that occurs instantaneously immediately following the first equation.
