The equilibrium condition refers to the state in which a system's macroscopic properties remain constant over time, indicating that the rates of opposing processes are equal. In the context of vapor-liquid systems, this condition signifies that the chemical potentials and fugacities of the vapor and liquid phases are equal, leading to no net change in the amount of substance in each phase. Understanding this balance is crucial for analyzing phase transitions and the behavior of mixtures in thermodynamic processes.
