The following equilibrium constants were determined at 1123 K:

C(s) + CO2(g) ⇌ 2CO(g) K'P = 1.30 × 10¹⁴ 

CO(g) + Cl2(g) ⇌ COCl2(g) K''P = 6.00 × 10^-3

Calculate the equilibrium constant at 1123 K for the reaction:

C(s) + CO2(g) + 2Cl2(g) ⇌ 2COCl2(g)

Write the equilibrium constant expression, KP Write the pressures in the following format:(PCO2)
