JEE Mains · Chemistry · STD 12 -1. Solution and colligative properties
A solution of two miscible liquids showing negative deviation from Raoult's law will have :
- A increased vapour pressure, increased boiling point
- B increased vapour pressure, decreased boiling point
- C decreased vapour pressure, decreased boiling point
- D decreased vapour pressure, increased boiling point
Answer & Solution
Correct Answer
(D) decreased vapour pressure, increased boiling point
Step-by-step Solution
Detailed explanation
Solution with negative deviation has \( \mathrm{P}_{\mathrm{T}}<\mathrm{P}_{\mathrm{A}^0} \mathrm{X}_{\mathrm{A}} +\mathrm{P}_{\mathrm{B}^0} \mathrm{X}_{\mathrm{B}} \) \( \mathrm{P}_{\mathrm{A}}<\mathrm{P}_{\mathrm{A}^0} \mathrm{X}_{\mathrm{A}} \)…
