Influence of different non-ionization reaction rates on the electron number density and the comparison with the influence of ionization reaction rate. (a) Reaction rate of \(N_{2} \rightleftharpoons N + N\), (b) reaction rate of \(O_{2} \rightleftharpoons O + O\), (c) reaction rate of \(NO \rightleftharpoons N + O\) and (d) reaction rate of \(N + O \rightleftharpoons NO^{ + } + e\).
