Question

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 = 2.22 × 10-4 atm. The partial pressure of the product, phosgene (COCl2), is ________ atm.
A) 7.34
B) 3.02 × 1015
C) 3.31 × 10-16
D) 3.31 × 104
E) 6.67 × 1011

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 3.31 × 104 atm. The answer is letter D.
