2 NO2 + O3 → N2O5 + O2
This is an oxidation-reduction (redox) reaction:
2 NIV - 2 e- → 2 NV (oxidation)
O0 + 2 e- → O-II (reduction)
NO2 is a reducing agent, O3 is an oxidizing agent.

- NO2 – Nitrogen dioxide
- Other names: Nitrogen(IV) oxide , Deutoxide of nitrogen , Nitrogen peroxide
- Appearance: Brown gas ; Reddish-brown gas or brown or yellow liquid with pungent odour ; Yellowish-brown liquid or reddish-brown gas (above 70°F) with a pungent, acrid odor. [Note: In solid form (below 15°F) it is found structurally as N2O4.]
