The vapor pressure of liquid octane, C8H18, is 100. mm Hg at 339 K.
A sample of C8H18 is placed in a closed, evacuated 552 mL container at a temperature of 339 K. It is found that all of the C8H18 is in the vapor phase and that the pressure is 68.0 mm Hg. If the volume of the container is reduced to 350 mL at constant temperature, which of the following statements are correct?
Choose all that apply.
A) No condensation will occur.
B) Only octane vapor will be present.
C) Some of the vapor initially present will condense.
D) The pressure in the container will be 107 mm Hg.
E) Liquid octane will be present.
