A given quantity of solute dissolves faster when it is ground into small particles than if it is i n the form of a large chunk because more surface area is exposed. The packet of granulated sugar exposes far more surface area to the solvent and dissolves more quickly than the sugar cube.

Answer:
The smaller one will "dissolve" faster because more of it surface area is exposed to the colliding molecules of the "solvent"; while the large molecules, because of its greater size will not expose as much "surface area"; therefore, dissolving more "slowly" in the "solvent".
