Question:
Assertion (A): Henry’s law constant (KH) decreases with increase in temperature.
Reason (R): As the temperature increases, solubility of gases in liquids decreases.
Assertion (A): Henry’s law constant (KH) decreases with increase in temperature.
Reason (R): As the temperature increases, solubility of gases in liquids decreases.
Reason (R): As the temperature increases, solubility of gases in liquids decreases.
Show Hint
Henry's law constant decreases with increasing temperature due to the decreasing solubility of gases.

- Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
- Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
- Assertion (A) is true, but Reason (R) is false.
- Assertion (A) is false, but Reason (R) is true.
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
According to Henry's law, the solubility of a gas in a liquid decreases as temperature increases, which in turn decreases the Henry’s law constant (KH). However, Reason (R) is false because the solubility of gases in liquids actually decreases as the temperature increases, not the other way around.
