N₂ (g) + O₂ (g) ⇌ 2NO (g)

Le Chatelier's principle basically states that whatever change we add into a closed system, the system is going to try to undo it---to counteract it.

If we add more O₂ (g), the system will try to reduce that added concentration in the reactants (oxygen is part of the reactants) by shifting the equilibrium to the products (shift to the right).

Shifting the equilibrium to the products (shift to the right)

This results in the following:

The concentration of N₂ (nitrogen) decreases.

The concentration of O₂ (oxygen) decreases.

The concentration of NO (nitric oxide) increases.
