Carbonyl chloride (COCl2), also called phosgene, wasused in World War I as a poisonous gas. The equilibriumconcentrations for the reaction between carbon monoxide andmolecular chlorine to form carbonyl chloride at 74°C are [CO] =1.2 multiplied by 10-2M, [Cl2] = 0.054 M, and[COCl2] = 0.14 M.
CO(g) + Cl2(g)reverse reaction arrowCOCl2(g)
