What happens to equilibrium when pressure changes?

It shifts to oppose the pressure change

When pressure increases, equilibrium shifts to...

The side with fewer moles of gas

When pressure decreases, equilibrium shifts to...

The side with more moles of gas

Why does equilibrium shift to fewer moles at high pressure?

To reduce pressure and oppose the change

Why does equilibrium shift to more moles at low pressure?

To increase pressure and oppose the change

Which reactions are affected by pressure changes?

Reactions involving gases

Ammonia formation equation

N2+3H22NH3N_2 + 3H_2 \rightleftharpoons 2NH_3

In ammonia formation, which side has fewer moles?
