The vapor pressure of liquid carbon disulfide, CS, is 40.0 mm Hg at 251 K. A sample of CS, is placed in a closed, evacuated container of constant volume at a temperature of 387 K. It is found that all of the CS, is in the vapor phase and that the pressure is 57.0 mm Hg. If the temperature in the container is reduced to 251 K, which of the following statements are correct? Choose all that apply. O Liquid carbon disulfide will be present. O The pressure in the container will be 40.0 mm Hg. O No condensation will occur. O Some of the vapor initially present will condense. Only carbon disulfide vapor will be present.
