Transcribed Image Text:### Phase Diagram for a Typical Liquid Mixture of Two Components
This diagram illustrates the phase behavior of a binary liquid mixture, depicting the relationship between temperature and composition. The x-axis represents the composition, ranging from 100% component A on the left to 100% component B on the right. The y-axis represents temperature.
**Key Features:**
- **Curves:**
- The **upper curve** represents the boundary for the vapor phase, where above this line, the mixture exists entirely as vapor.
- The **lower curve** represents the boundary for the liquid phase, with areas below this line existing entirely as liquid.
- **Regions:**
- In between the two curves lies a zone where both liquid and vapor phases coexist.
- **Points of Interest:**
- **Point `x`:** Represents a specific composition and temperature in the two-phase region.
- Draw a horizontal line from `x`, intersecting the vapor boundary at `y` and the liquid boundary at `w`.
- **Point `y`:** Corresponds to the vapor phase composition.
- **Point `w`:** Corresponds to the liquid phase composition.
- **Point `z`:** Illustrates the initial composition when the mixture begins to boil.
This phase diagram is crucial for understanding distillation and other separation processes where the relative volatility of the components is a key factor.

Transcribed Image Text:4. Using Figure 14.4, determine the boiling point of a liquid having a molar composition of 50% A and 50% B.
(Note: As Figure 14.4 is not provided, please refer to the relevant diagram or graph in your textbook or resources to determine the boiling point based on the molar composition.)
