Consider the Following Reaction: COCl₂(g) ⇌ CO(g) + Cl₂(g)

Consider the following reaction: COCl₂(g) ⇌ CO(g) + Cl₂(g)
A reaction mixture initially contains 1.6 mol L^-1 COCl₂. Determine the equilibrium concentration of CO if K_c for the reaction at this temperature is 8.33 × 10^-4 M. Calculate this based on the assumption that the answer is negligible compared to 1.6.

A) 4.2 × 10^-4 mol L^-1
B) 1.5 × 10^-3 mol L^-1
C) 3.7 × 10^-2 mol L^-1
D) 2.1 × 10^-2 mol L^-1
E) 1.3 × 10^-3 mol L^-1
