Question

Which of the following changes will increase the amount of solid solute able to be dissolved in a liter of liquid water? (3 points) decreasing pressure increasing temperature decreasing temperature increasing surface area

Answer 1

The solubility of a solute in a solvent is affected by the change in temperature. An increase in temperature increases solubility since the number of collisions between the solvent molecules and the solute particles increases leading to their breakdown of the solid solute. The correct answer is increasing temperature.

Answer 2

Answer: Option (b) is the correct answer.

Step-by-step explanation:

According to collision theory, more is the number of collisions between the particles more will be the rate of a chemical reaction.

Therefore, when we increase the temperature then there will be increase in kinetic energy of participating atoms. As a result, there will be more number of collisions between the solute and solvent atoms. Hence, solute will readily dissolve in the solvent.

Whereas when pressure is decreased then solvent and solute particles will be away from each other. Hence, less number of collisions will take place. As a result, formation of product will take more time.

Increasing the surface area will also make less contact between the solute and solvent particles due to which reaction will take time to complete.

Thus, we can conclude that increasing temperature will increase the amount of solid solute able to be dissolved in a liter of liquid water.
