Study Notes
Le-Chatelier's Principle
- When helium gas is added to the vessel at equilibrium, the concentration of SO₃ in the mixture decreases.
- The dissociation of SO₃ is affected by the addition of helium gas at constant temperature and volume.
- This causes the equilibrium position to shift towards the reactants, favoring the reverse reaction.
