Original PrepAtlas question. This is not an official College Board question.

For A + B ⇌ C, Kc = 4.0. Immediately after mixing, [A] = 0.50 M, [B] = 0.50 M, and [C] = 0.25 M. Which comparison predicts the net direction?

AQc = 1.0 > Kc, so net reverse reaction occurs.BQc = 4.0, so the mixture is already at equilibrium.CQc = 0.0625, so Kc changes to this value.DQc = 1.0 < Kc, so net forward reaction occurs.
