Answer:
Exposed surface area
Explanation:
The powdered calcium carbonate will react faster with hydrochloric acid than calcium carbonate chips due to the exposed surface area.
Powdered calcium carbonate has a larger surface area compared to the chips. And, the larger the surface area exposed on a body, the faster the reaction it will undergo.
For the same masses of a solid substance, the smaller the particle size of each form, the larger the surface area exposed to reaction.
The surface area exposed proportionally affects the rate of reaction.
