For a reaction A(g) <-> B(g) at equilibrium, K = 4.0. A new mixture has [A] = 0.20 M and [B] = 0.10 M.
Which direction will the system shift to reach equilibrium?
- A
Reverse, because Q = 0.5 < K
- Bcheck_circle
Forward, because Q = 0.5 < K
- C
No shift, because Q = K
- D
Forward, because Q > K
Explanation
Q = [B]/[A] = 0.10/0.20 = 0.5. Since Q < K, the reaction proceeds in the forward direction to make more products.
