Reaction between ammonia and nitrogen dioxide

Abstract

The reaction between ammonia and nitrogen dioxide has been studied in the temperature range 615–660 K.

The products of reaction are N₂, N₂O, NO and H₂O. A mechanism is proposed which leads to the following parameters: For NH₃+ NO₂[graphic omitted]NH₂+ HNO₂k₁= 10^{12.6 ± 0.3} exp (–115.69 ± 0.42/RT)cm³ mol^–1 s^–1(activation energies are expressed in kJ mol^–1) and for NH₂+ NO₂[graphic omitted] NH + HNO₂, NH₂+ NO [graphic omitted] N₂+ H₂O k₅/k₂= 10^{–2.30 ± 0.3} exp (26.78 ± 4.18/RT)
