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. D. There is not enough information to comment on the solution's vapor pressure at its boiling point

Question
Please help me I am trying to study for an upcoming final and was confused on some of the practice problems.
### Distillation Experiment: Understanding Vapor Pressure 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. D. There is not enough information to comment on the solution's vapor pressure at its boiling point. #### Explanation: Understanding the behavior of vapor pressure during distillation is essential for students in chemistry. Vapor pressure is determined by the components of the solution and their concentrations. Since *d-limonene* and water are immiscible, they do not mix into a single phase; instead, they form two separate phases, and the total vapor pressure is the sum of the individual vapor pressures of each component. As the distillation proceeds, the component with the higher vapor pressure (which distills off faster) will decrease in concentration, subsequently altering the overall vapor pressure.
