Why do gases always tend to be less soluble in liquids as the temperature is raised?
ChemistrySolutionsNEET
Options:
  • A Increasing temperature causes gases to dissociate into smaller particles, reducing their solubility in liquids.
  • B Dissolution of gas is an exothermic process. As the temperature is raised, the equilibrium shifts in reverse direction (Le-Chatelier's principle). It results in decrease of solubility of gases in liquid.
  • C As temperature rises, the density of the liquid decreases, making it harder for gas molecules to dissolve.
  • D Higher temperatures cause an increase in the polarity of liqu+ids, making them less likely to interact with gas molecules and reducing solubility.
