- Vapor pressure is the pressure inside a closed container when a liquid is in equilibrium with its own gas phase so the rate of evaporation is equal to the rate of condensation. When a non-volatile solute is dissolved in a volatile solvent, the vapor pressure of the solvent is reduced.

Jan 7, 2023 · Vapor pressure is a measure of the pressure exerted by a gas above a liquid in a sealed container. Strong intermolecular forces produce a lower rate of evaporation and a lower vapor pressure. Weak intermolecular forces produce a higher rate of evaporation and a higher vapor pressure.
Feb 5, 2019 · This example problem demonstrates how to use Raoult's Law to calculate the vapor pressure of two volatile solutions mixed together. Raoult's Law Example. What is the expected vapor pressure when 58.9 g of hexane (C 6 H 14) is mixed with 44.0 g of benzene (C 6 H 6) at 60.0 °C? Given: Vapor pressure of pure hexane at 60 °C is 573 torr.
