Phosgene (COCl₂) is a poisonous gas that dissociates at high temperature into two other poisonous gases, carbon monoxide and chlorine.
The equilibrium constant Kₚ = 0.0041 at 600°K. Find the equilibrium composition of the system after 0.124 mol of COCl₂ is allowed to reach equilibrium at this temperature, in a steel tank with a volume of 2 L.
