Solution

Kc = [SO₃]² / [SO₂]² [O₂] = 15.0

The Reaction Quotient, Qc is calculated exactly the same way from the given reaction mixture concentrations. Just substitute the given concentrations.

If Qc = Kc, the reaction mixture is in equilibrium.

If Qc > Kc, the reaction will shift to the left.

If Qc < Kc, the reaction will shift to the right.

For the first mixture, Qc = 15 , thus it is in equilibrium.

For the second mixture, Qc = 38.58, thus it will shift to left.

For the third mixture, Qc = 0.06, thus it will shift to the right.
