Final answer:
When SO₃ is removed in the equilibrium system, the equilibrium shifts to the right.
Step-by-step explanation:
For the equilibrium system described by the equation 2SO₂(g) + O₂(g) = 2SO₃(g) + heat, if SO₃ is removed, the equilibrium will shift to the Right. This is because, according to Le Chatelier's principle, when a reactant is removed, the system will try to replace it by producing more of that reactant. By shifting to the right, more SO₃ will be produced.
