Which of the following factors decreases the rate of solubility? a increases in pressureb increase in surface area of the solutec. decrease in temperatured. increased stirring

- C. decrease in temperature.

Explanations:- Solubility of a solid increases if the pressure is increased as the high pressure helps the solid to get dissolved in the solvent.

If the surface area of the solute is increased then more and more solute comes into the contact of the solvent and the solubility increases.

If the stirring is increased then it also helps the solute to get dissolved into the solvent.

Solubility of solids is directly proportional to the temperature.

So, if the temperature is decreased then solubility of the solute is also decreased.
