The vapor pressure of liquid methanol, CH3OH, is 40.0 mm Hg at 278 K. A sample of CH3OH is placed in a closed, evacuated container of constant volume at a temperature of 440 K. It is found that all of the CH,OH is in the vapor phase and that the pressure is 74.0 mm Hg. If the temperature in the container is reduced to 278 K, which of the following statements are correct? Choose all that apply. Liquid methanol will be present. Only methanol vapor will be present. | The pressure in the container will be 46.8 mm Hg. O No condensation will occur. Some of the vapor initially present will condense.
