Phosgene (cocl2) is formed by co and cl2 reacting in the presence of activated charcoal: co+ cl2 → coci, suppose the charge to a 5.00 liter batch reactor is a gas containing 40 mole% co and 60 mole% c12, and that the initial reactor conditions are 320°k and 2 bar. at the time when the concentration of phosgene in the reactor is 0.020 mol/liter, the concentration of co is ideal gas constant = 0.08314 liter bar/mol ok)
