The vapor pressure of liquid octane, C3H15, is 100. mm Hg at 339 K. A sample of CgH1g is placed in a closed, evacuated 526 mL container at a temperature of 339 K. It is found that all of the C3H13 is in the vapor phase and that the pressure is 58.0 mm Hg. If the volume of the container is reduced to 363 mL at constant temperature, which of the following statements are correct? Choose all that apply. O Some of the vapor initially present will condense. O Liquid octane will be present. ONo condensation will occur, O The pressure in the container will be 100. mm Hg. O Only octane vapor will be present.
