For the reaction

\mathrm{CO}(g) + \mathrm{Cl}_2(g) \rightleftharpoons \mathrm{COCl}_2(g)

1000\,\text{K}

, the equilibrium constant in terms of pressure is

K_p = 4.9

. An equilibrium mixture has partial pressures

P_{\mathrm{CO}} = 0.45\,\text{atm}

and

P_{\mathrm{COCl}_2} = 1.10\,\text{atm}

. Determine the equilibrium partial pressure of

\mathrm{Cl}_2
