When a volatile binary liquid mixture is heated and achieves its precise azeotropic composition, whi — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

An azeotrope is a constant boiling mixture (D), meaning it evaporates without a composition change, so $x_A = y_A$ (A). Because the vapour has the same composition as the liquid, fractional distillation cannot enrich one component further (B). Azeotropes only form in systems with *large* deviations from Raoult's law, making C false.
