Document Summary
When the rate of exit = the rate of entry, vapor is at equilibrium with the liquid. Vp is smaller in liquid with high imf1s. When vp = atmosphere pressure, liquid boils. Non-volatile solute presence of solute lowers vp zero vp blocks exit of solvent molecules from the surface, lowers the vp. Vp of solvent based on mole fraction of solvent. Psolvent = vp of solvent above solution. Volatile solute solute and solvent have vp. 2 components solute with volatile species a and b both a and b obey raoult"s law. Vap * ptotal boiling point elevation/freezing point depression phase diagram of pure substance shows the phase of the substance at a given pressure and temperature. Symbol the lines are called boundaries and on these boundaries the substance exists in two phases the line from the triple point to the critical point corresponds to vp of the substances as a function of temperature.
