Question

Elaborate on the reason why heating water up will increase the rate of dissolving for a solute.

A) The average kinetic energy of the solute molecules decreases with increasing temperature, and it changes the state of dissolution. The increased movement of the solute molecules causes them to break, and thus they dissolve more readily.
B) The molecules that make up the solution speed up with increasing temperature. This increase in kinetic energy allows the solvent molecules to more effectively hold themselves together and strengthen the intermolecular attractions between solute molecules.
C) The average kinetic energy of the solute molecules also increases with temperature, and it destabilizes the solid state. The increased vibration (kinetic energy) of the solute molecules causes them to hold together better, and thus they dissolve more readily.
D) The average kinetic energy of the molecules that make up the solution also increases with increasing temperature. This increase in kinetic energy allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Answer 1

D) The average kinetic energy of the molecules that make up the solution also increases with increasing temperature. This increase in kinetic energy allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Answer 2

Answer;

D) The average kinetic energy of the molecules that make up the solution also increases with increasing temperature. This increase in kinetic energy allows the solvent molecules to more effectively break apart the solute molecules that are held together by inter-molecular attractions.

Explanation;

• Solubility refers to the amount of a substance that can dissolve in a solution at a given temperature.
• Solubility increases with increase in temperature, this is because higher temperature of the solvents increases the kinetic energy of the particles in the solvent, thus they will vibrate more faster, which makes them to break apart the molecules of the solute that are held by inter-molecular forces more effectively.
