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.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
