The vapor pressure of liquid iodomethane, CH3I, is 40.0 mm Hg at 249 K. A sample of CH3I is placed in a closed, evacuated container of constant volume at a temperature of 372 K. It is found that all of the CH3I is in the vapor phase and that the pressure is 69.0 mm Hg. If the temperature in the container is reduced to 249 K, which of the following statements are correct? Choose all that apply. OLiquid iodomethane will be present. | Some of the vapor initially present will condense. O No condensation will occur. O The pressure in the container will be 46.2 mm Hg. O Only iodomethane vapor will be present.
