Chemistry - Vapor Phases and Condensation?

Posted on 2015-10-30 06:50:00 in Chemistry by SYLEZA

A sample of C2H5SH is placed in a closed, evacuated 540 mL container at a temperature of 260 K. It is found that all of the C2H5SH is in the vapor phase and that the pressure is 57.0 mm Hg. If the volume of the container is reduced to 385 mL at constant temperature, which of the following statements are correct?

Choose all that apply.
The pressure in the container will be 100. mm Hg.
Liquid ethane thiol will be present.
No condensation will occur.
Some of the vapor initially present will condense.
Only ethane thiol vapor will be present.
Update: The vapor pressure of liquid ethane thiol, C2H5SH, is 100. mm Hg at 260 K
