JEE PYQ: Solutions And Colligative Properties Question 15
Question 15 - 2020 (03 Sep Shift 1)
Henry’s constant (in kbar) for four gases $\alpha$, $\beta$, $\gamma$ and $\delta$ in water at 298 K is given below:
| $\alpha$ | $\beta$ | $\gamma$ | $\delta$ | |
|---|---|---|---|---|
| $K_H$ | 50 | 2 | $2 \times 10^{-5}$ | 0.5 |
(density of water $= 10^3$ kg m$^{-3}$ at 298 K)
(1). ($\alpha$ has the highest solubility in water at a given pressure)
(2). (solubility of $\gamma$ at 308 K is lower than at 298 K)
(3). (The pressure of a 55.5 molal solution of $\gamma$ is 1 bar)
(4). (The pressure of a 55.5 molal solution of $\delta$ is 250 bar)
Show Answer
Answer: (4)
Solution
For $\delta$: $P = 0.5 \times \frac{55.5}{55.5 + 1000/18} = 0.25$ kbar $= 250$ bar.
