Answer: Higher.
- A Lower
- B Higher
- C The same
- D Depends on solute only
Correct answer: B. Higher
Explanation: Boiling point elevation is a colligative property; dissolved solutes raise the boiling point.
Adding a non-volatile solute lowers the solvent's vapour pressure at every temperature, which is the root cause behind all four colligative properties: it shifts the freezing point down and the boiling point up.
