APFIVE Reaction Quotient and Equilibrium Shift
A 1.0 L vessel contains an equilibrium mixture of H2(g), I2(g), and HI(g) at 700 K where 2HI(g) ⇌ H2(g) + I2(g) with Kc = 0.016. If 0.10 mol of additional HI is injected without volume change, which statement correctly describes the system’s response?
A
Q < K; H2 and I2 combine to form more HI
B
Q = K; concentration changes but equilibrium position remains
C
Q > K; some added HI decomposes until Q = K
D
Q < K; some added HI decomposes until Q = K
