Consider the Following Reaction

Multiple Choice

Consider the following reaction:
COCl₂(g) ⇌ CO(g) + Cl₂(g0
A reaction mixture initially contains 1.6 M COCl₂.Determine the equilibrium concentration of CO if K_c for the reaction at this temperature is 8.33 × 10^-4.Calculate this based on the assumption that the answer is negligible compared to 1.6.

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