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
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 467 ∘C∘C . At equilibrium, the concentrations were measured and the following results obtained:
| Gas | Partial Pressure (atmatm) |
| COCO | 0.770 |
| Cl2Cl2 | 1.20 |
| COCl2COCl2 | 0.220 |
What is the equilibrium constant, KpKpK_p, of this reaction?
The following reaction was performed in a sealed vessel at 753 ∘C∘C :
H2(g)+I2(g)⇌2HI(g)H2(g)+I2(g)⇌2HI(g)
Initially, only H2H2 and I2I2 were present at concentrations of [H2]=3.50M[H2]=3.50M and [I2]=2.00M[I2]=2.00M . The equilibrium concentration of I2I2 is 0.0900 MM . What is the equilibrium constant, Kc, for the reaction at this temperature?
