Question

Match List - I with List - II.

Choose the correct answer from the options given below: 
 

• A. (A)-(II), (B)-(II), (C)-(III), (D)-(I)
• B. (A)-(I), (B)-(II), (C)-(III), (D)-(IV)
• C. (A)-(I), (B)-(III), (C)-(IV), (D)-(II)
• D. (A)-(I), (B)-(III), (C)-(II), (D)-(IV)

Hint:

The solubility of gases in liquids is inversely related to temperature and is also specific to each gas. Use Henry's law constants to predict how gases will behave under different conditions.

Answer 1

The Correct Option is B

The Henry's law constant (\( K_H \)) varies depending on the gas and its temperature. The correct matches are:
- (A) 145 K bar corresponds to CO$_2$ (I), which has the highest Henry's law constant.
- (B) 89 K bar corresponds to He (II), which is less soluble than CO$_2$.
- (C) 76.5 K bar corresponds to N$_2$ at 293 K (III), as nitrogen is less soluble than CO$_2$.
- (D) 1.67 K bar corresponds to N$_2$ at 303 K (IV), as the solubility of gases decreases with increasing temperature.
Thus, the correct answer is (A)-(I), (B)-(II), (C)-(III), (D)-(IV).
