According to the reaction equation:

by using ICE table:

CO (g) + Cl2 (g) ↔ COCl2 (g)

initial 0.025 0.0035 0

change - X - X + X

Equ (0.025-X) (0.0035-X) X

when:

Kp = P (COCl2) / P (CO}*P (Cl2) when Kp = 0.2

by substitution:

0.2 = X / (0.025-X) (0.0035-X) by solving this equation for X

∴ X = 1.74x10^-5
