A student is performing a distillation open to the atmosphere. The solution that the student is distilling consists of d-limonene and water. Approximately one half of the d- limonene from the citrus peels the student was using was distilled off. The student decides to add more water and perform a second distillation with the same setup to isolate more d-limonene. Which of the following statements is true about the second round of distillation? (Hint: d-limonene and water are immiscible) A. The vapor pressure of the solution at its boiling point decreases as the concentration of d-limonene decreases. B. The vapor pressure of the solution at its boiling point remains the same throughout the distillation. C. The vapor pressure of the solution at its boiling point increases as the concentration of d-limonene decreases.

Please help me with this, I am trying to prepare for my final exam next week and I am just completely lost 

**Distillation Process Analysis: d-Limonene and Water** **Scenario:** A student is performing a distillation open to the atmosphere. The solution that the student is distilling consists of d-limonene and water. Approximately one half of the d-limonene from the citrus peels the student was using was distilled off. The student decides to add more water and perform a second distillation with the same setup to isolate more d-limonene. **Question:** Which of the following statements is true about the second round of distillation? **Hint: d-limonene and water are immiscible.** **Options:** A. The vapor pressure of the solution at its boiling point decreases as the concentration of d-limonene decreases. B. The vapor pressure of the solution at its boiling point remains the same throughout the distillation. C. The vapor pressure of the solution at its boiling point increases as the concentration of d-limonene decreases. D. There is not enough information to comment on the solution’s vapor pressure at its boiling point. **Explanation:** In the context of immiscible liquids like d-limonene and water, the total vapor pressure at the boiling point is the sum of the individual vapor pressures of the two components. Since the boiling point is determined when the total vapor pressure equals atmospheric pressure, the distillation behavior can be analyzed accordingly. Understanding this principle is essential for predicting changes in vapor pressure in subsequent distillations.
