The solubility of gases decreases as temperature rises is the statement that is accurate about trends in solubility.

In chemistry, solubility is the ability of a body or a certain substance (called solute) to dissolve in a certain medium (called solvent).

The solubility decreases with increasing temperature because it causes an increase in the kinetic energy of the system, causing the gas molecules to tend to escape from the solution.If the temperature of the system is lowered, the kinetic energy drops, allowing the interaction of the gas with the solvent.At higher temperatures the solubility for solids and liquids increases, this is due to the kinetics or movement of the particles, by increasing their speed, the solid solute will dissolve more easily.

Therefore, we can conclude that at higher temperatures the solubility for gases decreases, since when heating a gaseous solution, the gas begins to move much faster and tries to “escape” from the solution.

Answer from: simplychan

"The solubility of gases decreases as temperature rises" statements about trends in solubility is accurate.

Option: D

Explanation:

A substance's solubility is the quantity of that component that is needed at a defined degree of temperature to produce a saturated solution in any set quantity of solvent. Some compounds like hydrochloric acid, ammonia, etc have solubility that reduces with rising temperature. They are both standard-pressure gases.

When heating a solvent with a gas absorbed in it, both the solvent and the solute spike in the kinetic energy.When the gaseous solute's kinetic energy rises, the molecules have a higher propensity to overcome the solvent molecules' connection and migrate to the gas phase. Thus, a gas's solubility reduces with rising temperature.
