The vapor pressure of liquid diethyl ether, C₂H5OC₂H5, is 100 mm Hg at 262 K. A sample of C₂H5OC₂H5 is placed in a closed, evacuated 527 mL container at a temperature of 262 K. It is found that all of the C₂H5OC₂H5 is in the vapor phase and that the pressure is 52.0 mm Hg. If the volume of the container is reduced to 314 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 diethyl ether will be present. Some of the vapor initially present will condense. No condensation will occur. Only diethyl ether vapor will be present.
