Web18 jan. 2024 · Vapor pressure is the pressure exerted by the vapor molecules of a substance in a closed system. It occurs at equilibrium, i.e., when the molecules are both vaporizing and condensing at the same rate at a particular pressure. Vapor pressure is directly related to the kinetic energy of a molecule. WebFor example, the vapor pressure of methanol at 25 C is 127.2 mm Hg compared to the vapor pressure of ethanol at 25 C which is 58.74 mm Hg. The vapor pressure of methanol will increase at a faster rate than ethanol meaning the plot of P vap vs. T(°C) for methanol would have a larger slope than the plot for ethanol giving it a steeper line.
