Phosgene (carbonyl chloride), COCl2, 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) Carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 469C. At equilibrium, the concentrations were measured and the following results obtained: What is the equilibrium constant, Kp, of this reaction? Express your answer numerically. Pearson The following reaction was performed in a sealed vessel at 725C : H2(g)+I2(g)2HI(g) Initially, only H2 and I2 were present at concentrations of [H2]=3.50M and [I2]=2.70M The equilibrium concentration of I2 is 0.0100M. What is the equilibrium constant, Kc, for the reaction at this temperature? Express your answer numerically
