Question

Give balanced equations for the synthesis of nitric oxide from ${\mathrm{NH}}_3\text{and}{\mathrm{O}}_2$ .

Answer 1

• Ammonia $\left({\mathrm{NH}}_3\right)$ reacts with oxygen $\left({\mathrm{O}}_2\right)$ in a variety of ways. The spiral will become white hot if we flow oxygen through a hot ammonia solution and lower it into the beaker without touching the liquid.
• Ammonia in the solution combines with oxygen on the platinum's surface to generate nitric oxide $\left(\mathrm{NO}\right)$ and water vapor $\left({\mathrm{H}}_2\mathrm{O}\right)$.
• Reaction will be:
  $4{\mathrm{NH}}_3\left(\mathrm{g}\right)+5{\mathrm{O}}_2\left(\mathrm{g}\right)\underset{800°\mathrm{C}}{\overset{\mathrm{Pt}}{\to }}4\mathrm{NO}\left(\mathrm{g}\right)+6{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+\text{Heat}$
