An equilibrium mixture contains {\rm{N}}_2 {\rm{O}}_4, (P = 0.27 atm) and {\rm{NO}}_2 (P = 1.2 atm) at 350 {\rm K}. The volume of the container is doubled at constant temperature.
Calculate the equilibrium pressure of {\rm N}_2{\rm O}_4 when the system reaches a new equilibrium.
Calculate the equilibrium pressure of {\rm NO}_2 when the system reaches a new equilibrium.
