8. A sealed vessel contains 0.25 M COC12, 0.11 M CO, and 0.11 M Cl2 at 668 K, which is an equilibrium mixture at this temperature. COCl2(g) = CO(g) + Cl2(g) a. When the temperature is increased and equilibrium is re-established, [COC12] = 0.18 M. Is the reaction endothermic or exothermic? How do you know? b. To the equilibrium mixture at 668 K, 0.25 M CO is added. Calculate the concentration of each gas at equilibrium.
