Read the following passage and answer the questions , Bodenstein carried out the determination of equilibrium constants of phosgene equilibrium by introducing CO and CI_2 at know pressure in a reaction bulb and measuring the equillibrium pressure from the attached monometer. in one experiment, CO at 342 nm and CI-2 at 351.4 nm were introduced . The equilibrium pressure was found to be 439.5nm . at equilibrium if partial pressure of COCI_2 "be" x "mm at " 127^@C.
