D) to calculate air pressure, the volume occupied by air is assumed constant. why is this incorrect? explain how the vapor pressure calculated and the resulting clausius-claperon plot are affected?

the volume occupied by air is not constant because as we add ethanol in it it will keep decreasing.

vapor pressure calculated and clausius-Claperon plot are affected because volume and vapor pressure are directly proportional.

Explanation:

by charle's law volume and temperature are directly proportional and vapor pressure is directly proportional to temperature thus volume and vapor pressure are also directly proportional by  this relation

lexy is right because she has the labeled s
