Phosgene (carbonyl chloride), COCl2COCl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. Phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: CO(g)+Cl2(g)⇌COCl2(g)CO(g)+Cl2(g)⇌COCl2(g) Carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 457 ∘C���C . At equilibrium, the concentrations were measured and the following results obtained:   Gas Partial Pressure (atmatm) COCO 0.790 Cl2Cl2 1.15 COCl2COCl2 0.190   What is the equilibrium constant, KpKpK_p, of this reaction?
