Hydrochloric acid reacts with the mineral calcite to produce carbon dioxide gas, water, and calcium chloride.
What are three things you could do to make the reaction occur more quickly?

The three things are increasing temperature, grinding calcite, and using catalyst are applied to make the reaction occur quickly.

Explanation:

To make the reaction occur more quickly the following three things are done.

Increasing temperature:

Increase in temperature increases the kinetic energy of molecules. This results in increase in the velocity and rate of collisions between reactants. Hence, greater the number of collisions between reactants per time greater will be the probability of formation of product per unit time.

Grinding Calcite:

Grinding of calcium carbonate results in the increase of surface area of calcite. So greater the surface area greater is the exposure of calcium carbonate to HCl molecules, thus the rate of formation of product increases.

Using Catalyst:

By using the catalyst it decreases the activation energy and increases the rate of reaction by following methods they are providing new pathway, weakening the bonds, providing surface area and holding up the reactant close to each other.
