A chunk of limestone, which is calcium carbonate, reacts with acid.

Question

How might you increase the rate of this reaction?

crush the limestone

remove any catalyst

decrease the temperature

add water to the acid

Answer 1

- Increase the surface area of the limestone by crushing it into smaller pieces. This will expose more limestone to the acid, speeding up the reaction.
- Add water to the acid, which will increase the concentration of reactive species and facilitate the reaction.
- Increase the temperature, which will provide more energy for the particles to collide and react.
- Add a catalyst that can increase the reaction rate without being consumed in the reaction itself.

Answer 2

so is it a b c or d

Answer 3

The ways to increase the rate of the reaction are A (crush the limestone), C (increase the temperature), and D (add water to the acid).

So the correct answer would be A, C, and D.
