The vapor pressure of liquid ethanol C_2H_5OH, is 40.0 mm Hg at 292 K. A sample of C_2H_5OH is placed in a closed, evacuated container of constant volume at a temperature of 410 K. It is found that all of the C_2H_5OH is in the vapor phase and that the pressure is 66.0 mm Hg. If the temperature in the container is reduced to 292 K, which of the following statements are correct? Choose all that apply. No condensation will occur. Liquid ethanol will be present. Only ethanol vapor will be present. The pressure in the container will be 47.0 mm Hg. Some of the vapor initially present will condense.
