3H₂ + N₂ --> 2NH₃

Apply LCP to identify how the system responds to the stress

• shifts to the right (favours forward reaction)

• shifts to the left (favours reverse reaction)

2SO₂(g)+O₂(g) ⇌ 2SO₃(g) + Heat

Increasing the temperature will...

• shift equilibrium right

• shift equilibrium left

• increase pressure

• have no change
