Decrease the particle size of the solute because the mass of the solute would be greater.
Decrease the particle size of the solute because the mass of the solute would be greater.

Increase the particle size of the solute because there would be a greater surface area exposed to the solvent.
Increase the particle size of the solute because there would be a greater surface area exposed to the solvent.

Increase the particle size of the solute because there would be a greater attraction between the solute and solvent particles.
Increase the particle size of the solute because there would be a greater attraction between the solute and solvent particles.

Decrease the particle size of the solute because it would increase how often the solute and solvent particles would collide.

Answer 1

To increase the rate of dissolution of a solute in a solution, you should:

Decrease the particle size of the solute because it would increase how often the solute and solvent particles would collide.

Decreasing the particle size increases the surface area of the solute in contact with the solvent, leading to more collisions and therefore a faster rate of dissolution.
