    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
