The reaction

has an equilibrium constant of 1.30 at 650°C. Carbon monoxide and steam both have initial partial pressures of 0.485 atm, while hydrogen and carbon dioxide start with partial pressures of 0.159 atm.

(a) Calculate the partial pressure of each gas at equilibrium.

(b) Compare the total pressure initially with the total pressure at equilibrium. Would that relation be true of all gaseous systems?
