### 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.
