Carbonyl chloride (COCI.), also called phosgene, was used in World War I as poisonous gas. The equilibrium concentrations for the reaction between carbon monoxide and molecular chlorine to form carbonyl chloride. CO(g) + Cl2(g) = COCI.(g) -2 at 74C are [CO] = 1.2 x 10 M, [Cl] = 0.054 M, and [COCI] = 0.14 M. What is the equilibrium constant (Kc) for this reaction
