Why would grinding up aluminum foil and reacting it with an aqueous chemical be better than just placing the whole foil in the aqueous solution?

• to decrease the rate of reaction

• to increase the molecular structure during the reaction

• to decrease the amount of catalyst during the reaction

• to increase the surface area of the reaction
