A 0.50 L vessel contains 1.0 mol of N2(g) and 3.0 mol of H2(g) at equilibrium at 400 K according to the following equation:N2(g) + 3H2(g) ⇌ 2NH3(g)If the volume of the vessel is suddenly decreased to 0.25 L, what will happen to the equilibrium position? Will the concentration of NH3 increase or decrease? Calculate the new equilibrium constant at this new volume.
