Each of the solutions above use water as the solvent. For l of the solutions except Ce2(SO4)3, the relationship between solubility and temperature is the same. Which statement summarizes the relationship?

When the water is at a lower temperature, kinetic energy is reduced, increasing solubility.
When the water is at a lower temperature, kinetic energy is increased, increasing solubility.
When the water is at a higher temperature, kinetic energy is increased, increasing solubility.
When the water is at a higher temperature, kinetic energy is reduced, increasing solubility.

The correct statement that summarizes the relationship between solubility and temperature for most of the solutions mentioned is:

When the water is at a higher temperature, kinetic energy is increased, increasing solubility.

In general, for most solid solutes, solubility tends to increase with an increase in temperature due to the increased kinetic energy of the molecules, which allows more solute to dissolve in the solvent.
