A 2.0 L-reaction flask initially contains 0.04 mol CO, 0.23 mol H2, and 0.60 mol CH3OH (methanol). If this mixture is brought in contact with a zinc oxide-chromium(III) oxide catalyst, the equilibrium shown below is attained.
CO(g) + 2 H2(g) <--> CH3OH(g)The equilibrium constant Kc for this reaction at 300°C is 1.1 10-2. What is Q?
