Question
Transcribed Image Text:**Question 3**
This question involves a temperature-composition liquid-vapor phase diagram of a binary system A-B. In the diagram, \( z_A \) represents the mole fraction of component A in the mixture. Below are the tasks to complete:
(a) Determine where a stable vapor phase exists (choose area I, II, or III).
(b) Identify the boiling point of a solution with \( x_A = 0.2 \). The boiling point, \( T_B \) (in °C, without decimals), is provided as: ____.
(c) Calculate the vapor phase mole fraction of A in equilibrium with the solution at \( x_A = 0.2 \). The mole fraction \( y_A \) (to 1 decimal place) is given as: ____.
(d) Using two theoretical plates, estimate the vapor phase mole fraction of A at the top of a fractional distillation column. The mole fraction \( y_A \) (to 2 decimal places) is: ____.
**Instructions**: Enter your answers according to the instructions.
**Graph Analysis**
The graph provided plots Temperature (°C) on the vertical axis against the mole fraction of A (\( z_A \)) on the horizontal axis. The graph displays two prominent curves:
- **Bubble Point Curve**: This curve represents the temperatures at which the first bubble of vapor forms as a liquid mixture is heated.
- **Dew Point Curve**: This curve shows the temperatures at which the last drop of liquid remains as a vapor mixture is cooled.
The graph marks three distinct areas:
- **Area I**: Located below the bubble point curve, indicating a single-phase liquid.
- **Area II**: Situated between the bubble point and the dew point curves, indicating a two-phase liquid-vapor mixture.
- **Area III**: Above the dew point curve, representing a single-phase vapor.
The diagram is fundamental for understanding phase changes and composition behavior in binary systems, especially in the context of distillation processes.
