Consider the following equilibrium system: 3SO₂(g)+O₂(g)⇌2SO₃(g). The addition of more O₂(g) to the system will shift the equilibrium position to the
- A. right, leading to the production of more SO₃(g)Correct
- B. right, leading to the production of more SO₂(g)
- C. left, leading to the production of more SO₂(g)
- D. left, leading to the production of more SO₂(g)
Explanation
By Le Chatelier's principle, adding more O₂ shifts the equilibrium to the right, favouring the production of more SO₃(g).
