Solubility of a gas in a liquid: |
Decreases with rise in temperature Increases with rise in temperature Does not depend on temperature First decreases and then increases with rise in the temperature |
Decreases with rise in temperature |
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). |
