Detailed Solution

The reaction, 4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(g) is an example of both displacement and redox reaction.
With the addition of oxygen, the nitrogen in ammonia is oxidised.
The above reaction is known as a redox reaction because both oxidation and reduction take place simultaneously.
It is a displacement reaction because oxygen displaces the H in NH3. A displacement reaction is a redox reaction and is typically followed by oxidation and reduction.
