At vaporâliquid equilibrium, a liquid with individual components in certain concentrations will have an equilibrium vapor in which the concentrations or partial pressures of the vapor components have certain values depending on all of the liquid component concentrations and the temperature.
(see state postulate)NOTEWhile the vapor pressure is similar to the saturation pressure, thevapor pressure refers to the pressure in a mixture of components(i.e., the total pressure is higher).OUTCOME:Describe the difference between the saturation and vapor pressures.
