Problem
A system at equilibrium for the reaction X₂(g) ⇌ 2 X(g) is suddenly injected with additional X₂(g), instantly doubling its concentration while the temperature remains constant. Which statement best describes the immediate relationship between Q and K and the sign of ΔG for the forward reaction?
(a) Q increases so Q > K, and ΔG for the forward reaction is positive
(b) Q remains equal to K, and ΔG remains zero
(c) Q decreases so Q < K, and ΔG for the forward reaction is negative
(d) Q decreases so Q < K, and ΔG for the forward reaction is positive
