Lated To Occur Via The Mechanism No 2 G No 2 G No G No 3 G Slow No 3 G No G O

2NO2 → 2NO (g) + O2 (g)

is postulated to occur via the mechanism

NO2 (g) + NO2 (g) → NO (g) + NO3 (g) (slow)

NO3 (g) → NO (g) + O2 (g) (fast)

What is an intermediate in this reaction?

O2 (g)

NO2 (g)

NO (g)

NO3 (g)
