The vapor pressure of liquid bromoethane, C₂H5Br, is 40.0 mm Hg at 246 K. A sample of C₂H5Br is placed in a closed, evacuated container of constant volume at a temperature of 365 K. It is found that all of the C₂H5Br is in the vapor phase and that the pressure is 61.0 mm Hg. If the temperature in the container is reduced to 246 K, which of the following statements are correct? Choose all that apply. Only bromoethane vapor will be present. The pressure in the container will be 41.1 mm Hg. Liquid bromoethane will be present. Some of the vapor initially present will condense. No condensation will occur.
