The vapor pressure of liquid iodomethane, ch3i, is 40.0 mm hg at 249 k. a sample of ch3i is placed in a closed, evacuated container of constant volume at a temperature of 404 k. it is found that all of the ch3i is in the vapor phase and that the pressure is 72.0 mm hg. if the temperature in the container is reduced to 249 k, which of the following statements are correct
choose all that apply
a. the pressure in the container will be 104 mm hg.
b. no condensation will occur.
c. some of the vapor initially present will condense.
d. only pentane vapor will be present.
e. liquid pentane will be present.
