Four samples of the same material with identical composition and mass were cut as shown in the diagrams below.

When subjected to the same chemical weathering, which sample will weather at the fastest rate?

1) A
2) B
3) C
4) D

D

Explanation:

Sample D will undergo the fastest rate when subjected to chemical weathering.

What is weathering?

From the given choices, option D will have the largest surface area exposed to chemical actions. It has more surface area compared to the others. The more broken a mass is, the more its surface area is.

Reaction rates are affected by:

The last cube has the highest surface area and will have the fastest rate of weathering.

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
