Equilibrium vapor pressures

Compare the vapor pressures of methanol,ethanol,acetic acid, water, and benzene. Which compund appears to have the strongest intermolecular forces at 100C If one compound has a higher equilibrium vapr pressure than another at a particular temperature, will it necessarily have a higher equilibrium vapor pressure at all temperatures? If not, give an example of two compiounds whose vapor pressure curves cross, and at what temperture they have roughly the same vapor pressure.

Compare the vapor pressures of methanol, ethanol, acetic acid, water, and benzene. Which compound appears to have the strongest intermolecular forces at 100 degree C? If one compound has a higher equilibrium vapor pressure than another at a particular temperature, will it necessarily have a higher equilibrium vapor pressure at all temperatures? If not, give an example of two compounds whose vapor pressure curves cross, and at what temperature they have roughly the same vapor pressure.

The vapor pressures at 20 degree Celsius are lifted below:
Methanol 128 mm Hg
Benzene 74.7 mm ...

Solution Summary

The equilibrium vapor pressure is examined. The strongest intermolecular forces are compared.
