Answer:
28.6
Step-by-step explanation:
Step 1: Write the balanced reaction at equilibrium
CO(g) + Cl₂(g) ⟺ COCl₂(g)
Step 2: Calculate the equilibrium partial pressure (in atm) of phosgene?
We will use the expression for the pressure equilibrium constant (Kp)
Kp = pCOCl₂ / pCO × pCl₂
pCOCl₂ = Kp × pCO × pCl₂
pCOCl₂ = 1.49 × 10⁸ × 4.38 × 10⁻⁴ × 4.38 × 10⁻⁴ = 28.6
