At 100 °C, the equilibrium constant for the reaction COCl₂(g) CO(g) + Cl₂(g) has the value K_c = 2.19 × 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 to achieve equilibrium.

(a) [COCl₂] = 2.00 × 10^-3 M, [CO] = 3.3 × 10^-6 M, [Cl₂] = 6.62 × 10^-6 M
(b) [COCl₂] = 4.50 × 10^-2 M, [CO] = 1.1 × 10^-7 M, [Cl₂] = 2.25 × 10^-6 M
(c) [COCl₂] = 0.0100 M, [CO] = [Cl₂] = 1.48 × 10^-6 M
