Question

3. The Kp for the reaction below is 1.49 × 108 at 100.0 °C:CO (g) + Cl2 (g) → COCl2 (g)In an equilibrium mixture of the three gases, PCO = PCl2 = 1.76 × 10-4 atm. The partial pressure of the product, phosgene (COCl2), is ________ atm.

Answer 1

In an equilibrium mixture of the three gases, PCO = PCl2 = 2.22 × 10-4 atm. The partial pressure of the product, phosgene (COCl2), is kp=(COCl2)/(CO)(Cl2) which is . So, the correct answer is 7.34.
