How does altering concentrations effect the equilibrium of the chemical equation N2 + O2 ⇌ 2NO?

Hey guys,
I'm learning about chemical equilibrium right now and am having some trouble with a practice question asking the effect on equilibrium of
1. Increasing/Decreasing concentration of oxygen
2. Increasing/Decreasing the concentration of nitrogen

with the reaction N2 (g) + O2 (g) ⇌ 2NO (g).

If anyone could help that would be great!

By Le Chatelier's Principle reducing the reactants shifts the reaction to the reactant side. Increasing the reactants shifts the reaction to the product side.

Explanation:

This problem is about Le Chatelier's Principle which says that if you modify a system in equilibrium, the system will adjust to seek a new equilibrium.

In this case:

If you increase the oxygen, you will consume more nitrogen and produce more NO.

If you decrease the oxygen, you will produce more nitrogen and reduce the amount of NO.

If you increase the nitrogen, you will consume more oxygen and produce more NO.

If you decrease the nitrogen, you will produce more oxygen and reduce the amount of NO.
