Question
The vapor pressure of liquid carbon disulfide, CS2, is 40.0 mm Hg at 251 K. A sample of CS2 is placed in a closed, evacuated container of constant volume at a temperature of 368 K. It is found that all of the CS2 is in the vapor phase and that the pressure is 54.0 mm Hg. If the temperature in the container is reduced to 251 K, which of the following statements are correct? Choose all that apply.
No condensation will occur.
Liquid carbon disulfide will be present.
Some of the vapor initially present will condense.
The pressure in the container will be 40.0 mm Hg.
Only carbon disulfide vapor will be present.
Explanation / Answer
With the vapor pressure for liquid CS being 40 mmHg at 251 K.
when a sample of CS2(l) was placed in an evacuated container at constant volume at temperature 368 K. All th CS2 would be in vapor phase. The new pressure is 54 mmHg. Now If temperature is reduced to 251 K. The true statements would be,
Liquid carbon disulfide will be present
Some of the vapor initially present will condense
