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 414 K. It is found that all of the CH3I is in the vapor phase and that the pressure is 59.0 mm Hg. If the temperature in the container is reduced to 249 K, which of the following statements are correct? Choose all that apply. O Liquid iodomethane will be present. O The pressure in the container will be 40.0 mm Hg. O Only iodomethane vapor will be present. No condensation will occur. OSome of the vapor initially present will condense.
