Nitric acid is made by reaction of nitrogen dioxide (NO2) with water. ... Nitric oxide is then reacted with oxygen in air to form nitrogen dioxide. 2 NO (g) + O2 (g) → 2 NO2 (g) (ΔH = −114 kJ/mol) This is subsequently absorbed in water to form nitric acid and nitric oxide...

hope!!...it helps uhh...❣️
