Reaction between ammonia and nitrogen dioxide

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= 1012.6 ± 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)
