16.) Why increasing temperature of the solvent well speed up the dissolving process?
Beacause it brings _________
a. more solute to crystallize
b. less solute molecules to the solvent
c. fresh solvent into contact with more solute
d. more solvent molecules to collide with the solute

Answer:
D
Explanation:
Heating up a solvent gives the molecules more kinetic energy. The increased rapid motion means that the solvent molecules collide with the solute with greater frequency, and that the collisions occur with more force. Both factors increase the rate at which the solute dissolves.
