Question

Which among the following is true for the value of Henry’s law constant \(K\)?

• A. is greater for gases with higher solubilities
• B. first increases and then decreases with increase in temperature
• C. increases with increase in temperature
• D. is same for all gases

Hint:

Higher value of Henry’s law constant means lower solubility of gas.

Answer 1

The Correct Option is C

Step 1: Recall Henry’s law.
Henry’s law states that solubility of a gas in a liquid is directly proportional to its partial pressure.
Step 2: Effect of temperature.
Gas solubility decreases with increase in temperature, which means Henry’s law constant increases.
Step 3: Conclusion.
Therefore, Henry’s law constant increases with increase in temperature.
