Phosgene is a deadly gas and its use in warfare has been
outlawed. The gas decomposes at elevated temperature:
COCl2(g) ⇄ CO(g) +
Cl2(g) Keq
8.3 × 10-4 at 352°C
What are the pressures at equilibrium if a 2.55 L metal container is charged with 2.00 bar of phosgene at 25°C and then heated to 352°C?
(pCO)eq = (pCl2)eq = 4.03×10-2bar
(pCOCl2)eq = 1.96 bar
