Question

A 3 L flask is filled with 0.45 mol SO₃, 0.50 mol SO₂, and 0.20 mol O₂, and allowed to reach equilibrium. Assume the temperature of the mixture is chosen so that Kc = 0.12. Predict the effect on the concentration of SO₃ as equilibrium is achieved by using Q, the reaction quotient.

2SO₃₍g) ⇆ 2 SO₂(g) + O₂(g)

[SO3] will decrease because Q > K.
[SO3] will decrease because Q < K.
[SO3] will increase because Q < K
[SO3] will increase because Q > K.
[SO3] will remain the same because Q = K.
