The solution to Equilibrium constant
A certain gas mixture held at 395C has the following initial partial pressures: P(Cl2) = 351.4 torr; P(CO) = 342.0 torr and P(COCl2) = 0. At equilibrium, the total pressure is 439.5 torr. The volume is held constant. Find Kp for the reaction: Cl2(g) + CO(g) = COCl2(g)
