Hydrogen and carbon dioxide react at a high temperature to give water and carbon monoxide.

(a) Laboratory measurements at 986°C show that there are 0.11 mol each of CO and H₂O vapor and 0.087 mol each of H₂ and CO₂ at equilibrium in a 50.0-L container. Calculate the equilibrium constant for the reaction at 986°C.
(b) Suppose 0.010 mol each of H₂ and CO₂ are placed in a 200.0-L container. When equilibrium is achieved at 986°C, what amounts of CO(g) and H₂O(g), in moles, would be present? [Use the value of K_c from part (a).]
