To increase the rate at which a solute dissolves, the following options apply:
-
b) increasing temperature: Higher temperatures typically increase the kinetic energy of the molecules, helping the solute to dissolve more quickly.
-
c) stirring: Stirring helps to distribute the solute throughout the solvent, allowing it to interact more with the solvent particles and dissolve faster.
-
e) increasing surface area: Increasing the surface area of the solute (for example, by grinding it into smaller pieces) allows more solute to come into contact with the solvent, facilitating a quicker dissolution.
The correct options to select are: b, c, and e.
Options a (decreasing temperature) and d (decreasing surface area) would not increase the rate of dissolution.
