Murray · Answer 1

10 mm2

Explanation:

correct!

Ibrahim Cuevas · Answer 2

10 mm2

Explanation:

The solute with 10 mm2 surface area will dissolve the quickest.

According to the law of reaction, the rate of reaction is directly proportional to the surface area of the reactants, provided that all other conditions are constant.

Hence, if four solutes with with the same properties but different surface areas are separately dissolved in a solvent under the same conditions, the solute with the highest surface area will dissolve the quickest while the one with the lowest surface area will dissolve the slowest.
