(A) The reaction N₂O₄(g) ⇌ 2 NO₂(g) is at equilibrium in a 3.00 L cylinder. What would be the effect on the concentrations of N₂O₄(g) and NO₂(g) if the pressure were doubled (that is, cylinder volume decreased to 1.50 L)?

(B) How is the equilibrium amount of H₂(g) produced in the water–gas shift reaction affected by changing the total gas pressure or the system volume? Explain.
