The correct Answer is:
To analyze the given statements about azeotropes, we will evaluate each statement step by step. ### Step 1: Evaluate Statement 1 **Statement 1:** Azeotrope is a binary mixture formed by ideal solutions. - Azeotropes are defined as mixtures that have a constant boiling point and maintain the same composition in both the liquid and vapor phases during the phase transition. - Ideal solutions are characterized by the property that the vapor and liquid phases have different compositions. In ideal solutions, Raoult's law applies perfectly, which means that the partial vapor pressures of the components are proportional to their mole fractions in the solution. - Therefore, since azeotropes do not behave like ideal solutions, **Statement 1 is incorrect**. ### Step 2: Evaluate Statement 2 **Statement 2:** Azeotrope boils with unchanged composition. - Azeotropes do indeed boil at a constant temperature and maintain the same composition in both the liquid and vapor phases throughout the boiling process. - This means that when an azeotropic mixture is heated, it will vaporize without changing its composition, which is a defining characteristic of azeotropes. - Therefore, **Statement 2 is correct**. ### Conclusion - **Statement 1 is false** (as azeotropes are formed from non-ideal solutions). - **Statement 2 is true** (as azeotropes boil with unchanged composition). ### Final Answer - Statement 1: False - Statement 2: True
