Question

Why does the rate of dissolution for a gas decrease as the temperature of a solvent increases?

more space for the solute to escape


less space for the solute molecules


less space between solvent molecules


more collisions between solute and solvent molecules

Answer 1

As the kinetic energy of the gaseous solute increases, its molecules have a greater tendency to escape the attraction of the solvent molecules and return back to the gas phase. As a result, the solubility of a gas decreases as the temperature increases.
