liquid-vapor equilibrium liquid-vapor equilibrium[′lik·wəd ¦vā·pər ‚ē·kwə′lib·rē·əm] (physical chemistry) The equilibrium relationship between the liquid and its vapor phase for a partially vaporized compound or mixture at specified conditions of pressure and temperature; for mixtures, it is expressed by K = x/y, where K is the equilibrium constant, x the mole fraction of a key component in the vapor, and y the mole fraction of the same key component in the liquid. Also known as vapor-liquid equilibrium. |
