At 100oC the equilibrium constant for the reaction below has the value of Keq = 2.19 x 10−10. COCl2(g) ⇄ CO(g) + Cl2(g) Are the following mixtures of COCl2, CO, and Cl2 at equilibrium? If not, indicate the direction that the reaction must proceed to achieve equilibrium. (i) PCOCl2 = 5.00 × 10−2 atm; PCO = 3.31 × 10−6 atm; PCl2 = 3.31 × 10−6 atm (ii) PCOCl2 = 3.50 × 10−3 atm; PCO = 1.11 × 10−5 atm; PCl2= 3.25 × 10−6 atm
