Web6. level 1. · 9 mo. ago. An azeotrope forms when the free energy of either molecule type in the vapor phase is exactly equal to their free energy in the liquid phase, and therefore no further spontaneous phase change will occur. It can be difficult to predict when this will happen, but they generally emerge between very similar looking molecules. WebMay 8, 2024 · An azeotrope (/əˈziːəˌtroʊp/) or a constant boiling point mixture is a mixture of two or more liquids whose proportions cannot be altered or changed by simple distillation. It further goes on to give the reason; This happens because when an azeotrope is boiled, the vapour has the same proportions of constituents as the unboiled mixture.
