The boiling points of pure components of a binary system ________________ with increase in total pressure of the system ?
Correct answer: D. Increases
- A. Decreases
- B. May increase or decrease, depends on the system
- C. Remains unchanged
- D. Increases
Explanation
A pure liquid boils when its vapour pressure equals the system pressure. Since vapour pressure rises with temperature, a higher total pressure requires a higher boiling temperature.
