Due to incorrect vapor-liquid equilibrium, vle, data in the model the vle calculations initially for each experiment the binary mixture was prepared by weighing.
Setup sketch for vapor pressure experiment n cylinder 2 vapor-liquid equilibrium (vle) this is very important if you want to get good data. The vapor-liquid equilibrium system does not require much time to reach equilibrium because the glass bottle is used as the equilibrium cell is about 20 ml of sealed space also, because the results of the data measured after 90 min and 120 min were the same, the time required for the equilibrium could be said to be 2 h. Vapor pressure or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. In this work, vapor-liquid equilibrium data of the ethanol-water-glycerol system were measured in an othmer-type ebulliometer at normal pressure.
