Why does the solubility of a gas solute in a liquid solvent decrease with increasing temperature?
With an increase in temperature, the solvent molecules have less kinetic energy, so they collide with the solute less vigorously. That action facilitates the disruption of particle-to-particle attractions in the solute.
With an increase in temperature, the molecules have more kinetic energy, so it is easier for solute molecules to escape from the solution.
