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 458 âC . At equilibrium, the concentrations were measured and the following results obtained:
Gas Partial Pressure
(atm) CO 0.730 Cl2 1.28 COCl2 0.160
What is the equilibrium constant, Kp, of this reaction?
Express your answer numerically.
Part B
The following reaction was performed in a sealed vessel at 772 âC :
H2(g)+I2(g)â2HI(g)
Initially, only H2 and I2 were present at concentrations of [H2]=3.30M and[I2]=2.70M. The equilibrium concentration of I2 is 0.0900 M . What is the equilibrium constant, Kc, for the reaction at this temperature?
Express your answer numerically.
