Solubility of a gas in a liquid:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Decreases with rise in temperature
Solubility of gases in liquids decreases with rise in temperature. When dissolved, the gas molecules are present in liquid phase and the process of dissolution can be considered similar to condensation and heat is evolved in this process. According to Le Chatelier’s Principle As dissolution is an exothermic process, the solubility should decrease with increase of temperature (backward reaction).
