Part A 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)âCOCl2(g) Carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 462 âC . At equilibrium, the concentrations were measured and the following results obtained: Gas Partial Pressure (atm) CO 0.750 Cl2 1.24 COCl2 0.240 What is the equilibrium constant, Kp, of this reaction? Express your answer numerically. Kp = SubmitHintsMy AnswersGive UpReview Part Incorrect; Try Again; 5 attempts remaining Deriving concentrations from data In Part A, you were given the equilibrium pressures, which could be plugged directly into the formula for K. In Part B however, you will be given initial concentrations and only one equilibrium concentration. You must use this data to find all three equilibrium concentrations before you can apply the formula for K. Part B The following reaction was performed in a sealed vessel at 777 âC : H2(g)+I2(g)â2HI(g) Initially, only H2 and I2 were present at concentrations of [H2]=3.90M and [I2]=2.45M. The equilibrium concentration of I2 is 0.0700 M . What is the equilibrium constant, Kc, for the reaction at this temperature? Express your answer numerically.
