a. Use the CO, phase diagram to answer the following questions. (4 points) i. Circle any point on the CO2 phase diagram that represents a system at dynamicequilibrium. (2 points)

ii. What is happening at that point that makes it a dynamic equilibrium? (2 points) \text { Use the reaction } 2 \mathrm{NO}_{2}(g) \rightleftharpoons \mathrm{N}_{2} \mathrm{O}_{4}(g) \text { to answer the following questions. (6 points) } i. What does Le Châtelier's principle predict would happen to the equilibrium conditions ifN,04 were added to the system? (2 points) ii. What would happen to the equilibrium if the pressure were increased? (2 points)
