a.) 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?

b.)Hydrogen bromide dissociates when heated according to the following equation.

2 HBr(g) <---> H2(g) + Br2(g)

The equilibrium constant Kc equals 1.6 10-2 at 200°C. What are the moles of substances in the equilibrium mixture at 200°C if we start with 0.021 mol HBr in a 1.3-L vessel?

HBr(g)__ mol

H2(g)___mol
