The decomposition of N2O5 in the gas phase to N2O4 and O2 is complicated by the subsequent decomposition of N2O4 to NO2 (presence indicated by brown color) in a rapidly established equilibrium. The reacting system can then be modeled by the kinetics scheme N2O5 (A) → N2O4 (B) +(1/2) O2 (C) N2O4 2 NO2 (D)
