Answer:
d. increases the surface area of solute that is exposed to solvent.
Explanation:
Surface area is a mathematical term, used to refer to the total area that a solid substance occupies. In this case, the more fragmented a solid substance is, the larger its surface area will be. From this we can conclude that crushing a solid substance increases the rate at which the substance dissolves because crushing increases the surface area of the solute that is exposed to the solvent.
