Step 1: Ammonia oxidation to nitric oxide \mathrm{(NO)}

\mathrm{4 \mathrm{NH}_3+5 \mathrm{O}_2 \rightleftharpoons 4 \mathrm{NO}+6 \mathrm{H}_2 \mathrm{O}}

Step 2: Nitric oxide oxidation to nitrogen dioxide \mathrm{(NO_{2})}

\mathrm{2NO+O_{2}\rightleftharpoons 2NO_{2}

Step 3: Nitrogen dioxide absorption in water to form nitric acid

\mathrm{3NO_{2}+H_{2}O\rightleftharpoons 2HNO_{3}+NO}

These reactions represent the key steps involved in the Ostwald process, where ammonia is sequentially oxidized to nitric oxide and then to nitrogen dioxide. Finally, nitrogen dioxide reacts with water to form nitric acid.
