Assertion: Azeotropic mixtures are formed only by non-ideal solutions and they may have boiling points either greater than both the components or less than both the components.
Reason: The composition of the vapor phase is the same as that of the liquid phase of an azeotropic mixture.

Explanation:
Azeotropic mixtures are special types of liquid mixtures that have constant boiling points and constant composition at a specific pressure. They are formed when the vapor and liquid phases have the same composition, and the vapor phase cannot be further enriched or depleted of any component by simple distillation.

Assertion Explanation:
Azeotropic mixtures are formed only by non-ideal solutions because ideal solutions follow Raoult's law, which states that the partial vapor pressure of each component in the solution is directly proportional to its mole fraction in the liquid phase. This means that the composition of the vapor phase would be different from the liquid phase, and simple distillation could separate the components.

In non-ideal solutions, the intermolecular forces between the solute and solvent molecules are not similar, leading to deviations from Raoult's law. These deviations result in azeotropic behavior, where the composition of the vapor phase is the same as that of the liquid phase. This is why azeotropic mixtures are formed only by non-ideal solutions.

The boiling points of azeotropic mixtures can be either greater than both the components or less than both the components. This is because the composition of the azeotropic mixture is different from the individual components, leading to a change in the boiling point. In some cases, the azeotropic mixture may have a higher boiling point than both components, while in other cases, it may have a lower boiling point.

Reason Explanation:
The composition of the vapor phase is the same as that of the liquid phase of an azeotropic mixture. This is because azeotropic mixtures have constant boiling points and constant composition. During the process of vaporization, the vapor phase is enriched or depleted of components to maintain the same composition as the liquid phase. This is why the composition of the vapor phase is the same as that of the liquid phase in an azeotropic mixture.

Conclusion:
The reason provided is a correct explanation of the assertion. Azeotropic mixtures are formed only by non-ideal solutions, which deviate from Raoult's law. The composition of the vapor phase is the same as that of the liquid phase in an azeotropic mixture, allowing for constant boiling points and constant composition. The boiling points of azeotropic mixtures can be either greater than both the components or less than both the components, depending on the specific composition of the mixture.
