Kc for CO(g) +H2O(g) ⇌ CO2(g) +H2(g) at 986°C is 0.63. A mixture of 1 mole H2O(g) and 3 moles CO(g) is allowed to react to come to an equilibrium. The equilibrium pressure is 2.0 atm.
(a) How many moles of H2 are present at equilibrium?
(b) Calculate the partial pressure of each gas at equilibrium.
