At 100 C the equilibrium constant for the reaction COCl2(g) ?? CO(g) + Cl2(g) has a value of Kc = 2.19 X 10 ^-10. Are the following mixtures of COCl2, CO, and Cl2 at 100 C at equilibrium? If not, indicate the direction that the reaction must proceed in order to reach equilibrium.
a) [COCl2] = 2.00 x 10 ^-3 M, [CO] = 3.3 X 10 ^-6 M, [Cl2] = 6.62 X 10^-6 M
b) [COCl2] = 4.50 x 10 ^-2 M, [CO] = 1.1 X 10 ^-7 M, [Cl2] = 2.25 X 10^-6 M
c) [COCl2] = 0.010 M, [CO] = [Cl2] = 1.48 X 10^-6 M
