Question
Below is a graph of a T-x-y plot for a non-ideal mixture of A and B, where A is the more volatile component. Three different points on the plot are highlighted with boxes A, B, and C.

### Questions

1. **What do the temperatures at points A, B, and C correspond to?**
2. **What is the relative volatility at 70 degrees C?**
3. **Sketch a x-y plot for component A.**

### Graph Explanation

- **X-axis (Bottom):** Represents the mole fraction of component A, indicated as \( x_A, y_A \), ranging from 0 to 1.
- **Y-axis (Left):** Represents the temperature in degrees Celsius (°C), ranging from 55°C to 85°C.
- **Curves:**
  - The lower curve seems to represent the bubble point curve.
  - The upper curve seems to represent the dew point curve.
  
- **Highlighted Points:**
  - **Point A:** Located at approximately \( x_A = 0.0 \) and \( y_A = 0.0 \) with a temperature of around 80°C.
  - **Point B:** Located at approximately \( x_A = 1.0 \) and \( y_A = 1.0 \) with a temperature of around 60°C.
  - **Point C:** Located at approximately \( x_A = 0.5 \) and \( y_A = 0.3 \) with a temperature of around 70°C.

Expert Solution
Step 1: The temperatures at points A, B, and C correspond to the following


  1. The temperatures at points A, B, and C correspond to the following:

    • Point A: The temperature at which the vapor and liquid phases are in equilibrium, and the composition of the vapor phase is equal to the composition of the liquid phase.
    • Point B: The temperature at which the vapor phase is richer in the more volatile component (A) than the liquid phase.
    • Point C: The temperature at which the vapor phase is poorer in the more volatile component (A) than the liquid phase.
