Unformatted text preview: Q = K Reaction IS already at equilibrium: no shift. Q > K Product concentration is too high: Reaction must shift to the left to reach equilibrium Q < K Product concentration is too low: Reaction must shift to the right to reach equilibrium Example K = 49 at 450 o C for this reaction: H 2(g) + I 2(g) ↔ 2HI (g) If 0.22 mole of I 2 , 0.22 mole of H 2 , and 0.66 mole of HI were put into an evacuated 1.00-liter container, would the system be at equilibrium? If not, what must occur to establish equilibrium?...
