Answer:
The liquid-vapor equilibrium is reached when the chemical potentials of the substance are equal in both phases at a certain temperature and pressure. The evaporation rate is equal to the condensation
Explanation:
The most important considerations in the liquid-vapor balance are the following:
-The vapor phase is considered an ideal gas mixture.
-The liquid phase is considered an ideal solution.
Said equilibrium state occurs when the steam pressure is reached. This depends on the temperature, the nature of the components and the composition in each phase. For example, consider an ideal solution, the vapor pressure will be proportional to the moles of each component in the liquid phase and the vapor pressure of the pure substance at a temperature, according to Raoult's law.
