Given the reaction
QuSO4(s) Cu2+(ag) SO42 + (aq)
The CuSO4(s) dissolves more rapidly when it is powdered because the increase in
surface area allows for
1) increased exposure of solute to solvent
2) decreased exposure of solute to solvent
3) increased solute solubility
4) decreased solute solubility
