I have the following equilibrium:

N2 (g) + 3H2 (g) ⇌ 2NH3 (g)
If I increase the pressure, then will my
reaction shift to the right or to the left?

Answer:

If you increase the pressure of a reaction that involves gas molecules, the equilibrium will shift towards the side with fewer gas molecules to relieve the stress of the increased pressure.

In this case, the reaction has 4 moles of gas molecules on the left side (1 mole of N2 and 3 moles of H2) and 2 moles of gas molecules on the right side (2 moles of NH3). Therefore, the equilibrium will shift towards the right to decrease the number of gas molecules and relieve the stress of the increased pressure.
