Question 35 - 2019 (10 Apr Shift 2)
1 g of a non-volatile non-electrolyte solute is dissolved in 100 g of two different solvents A and B whose ebullioscopic constants are in the ratio of 1 : 5. The ratio $\frac{\Delta T_b(A)}{\Delta T_b(B)}$ is:
(1). (5 : 1)
(2). (10 : 1)
(3). (1 : 5)
(4). (1 : 0.2)
Show Answer
Answer: (3)
Solution
$\frac{(\Delta T_b)_A}{(\Delta T_b)_B} = \frac{(K_b)_A}{(K_b)_B} = \frac{1}{5}$.
