How to make limestone react faster in hydrochloric acid.

so here is the questionL:

We have a piece of limestone in hydrochloric acid. It is not reacting very fast. Explain 3 ways in which we could make it react faster:

please give some information on what you decide.

1. Crush the limestone into smaller pieces - to give a higher surface area, which would increase the chance of collisions between particles, hence speeding up the reaction.

2. Increase the concentration of hydrochloric acid - this means there are more acid particles that can collide with the limestone, which speeds up the reaction.

3. Increase the temperature - which will give all the particles more kinetic energy, meaning they move around faster and are more likely to collide and react. This increases the speed of reaction.

use a catalyst.
