Question
The vapor pressure of liquid pentane, C5H12, is 100. mm Hg at 260 K. A 8.35E-2 g sample of liquid C5H12 is placed in a closed, evacuated 350. mL container at a temperature of 260 K.
Assuming that the temperature remains constant, will all of the liquid evaporate? _____yesno
What will the pressure in the container be when equilibrium is reached? ______mm Hg
2.
The vapor pressure of liquid chloroform, CHCl3, is 100. mm Hg at 283 K.
A sample of CHCl3 is placed in a closed, evacuated 539 mL container at a temperature of 283 K. It is found that all of the CHCl3 is in the vapor phase and that the pressure is 75.0 mm Hg. If the volume of the container is reduced to 336 mL at constant temperature, which of the following statements are correct?
Choose all that apply.
A. No condensation will occur.
B. Liquid chloroform will be present.
C. Some of the vapor initially present will condense.
D. Only chloroform vapor will be present.
E. The pressure in the container will be 120 mm Hg.
