The vapor pressure of liquid octane, C8H18, is 40.0 mm Hg at 318 K. A sample of C8H18 is placed in a closed, evacuated container of constant volume at a temperature of 446 K. It is found that all of the C8H18 is in the vapor phase and that the pressure is 60.0 mm Hg. If the temperature in the container is reduced to 318 K, which of the following statements are correct? Choose all that apply. The pressure in...

The vapor pressure of liquid octane, CgH1s, is 100. mm Hg at 339 K in a closed, evacuated 544 ml container at a temperature of 339 K. It is found that all of the CgHis is in the vapor phase and that the pressure is 61.0 mm Hg. If the volume of the container is reduced to 345 ml at the following statements are correct? constant temperature, which...
A liquid placed in a closed container will evaporate until equilibrium is reached. At equilibrium, which of the following statements is false? A. The partial pressure exerted by the vapor molecules is called the vapor pressure of the liquid. B. Liquid molecules are still evaporating. C. The number of vapor molecules remains essentially constant. D. The partial pressure of the vapor is constant. E. The boundary (meniscus) between liquid and vapor disappears.
