Question

Match the following:

Property	Expression
A. π	I. Kb · m
B. ΔTf	II. Kf · m
C. ΔTb	III. CST
D. (P0 - P) / P0	IV. (n1 / (n1 + n2))

• A. A – III, B – II, C – I, D – IV
• B. A – IV, B – II, C – I, D – III
• C. A – II, B – I, C – IV, D – I
• D. A – I, B – III, C – II, D – IV

Hint:

Remember colligative property formulas to match variables correctly.

Answer 1

The Correct Option is A

- A. $\pi$ (osmotic pressure) ∝ $CST$ ⇒ A – III
- B. $\Delta T_f$ (freezing point depression) = $K_f \cdot m$ ⇒ B – II
- C. $\Delta T_b$ (boiling point elevation) = $K_b \cdot m$ ⇒ C – I
- D. Relative lowering of vapor pressure = $\dfrac{P^0 - P}{P^0} = \dfrac{n_2}{n_1 + n_2}$ ⇒ D – IV
