Pressure and equilibrium position

Q05.3 1 mark

Sulfur dioxide (SO₂) reacts reversibly with oxygen (O₂) to produce sulfur trioxide (SO₃):

2 SO2(g)+O2(g)⇌2 SO3(g)2\,SO_2(g) + O_2(g) \rightleftharpoons 2\,SO_3(g)

The pressure is decreased.

What is the effect on the position of the equilibrium? Tick one box.
