The given factors are matched to the effect it would have on the reaction rate are as follows.

- Crushing the antacid tablet

- Using many antacid tables

- Adding a catalyst to the water

- Cooling the water during the reaction

- Adding food coloring to the water

Explanation:

When antacid tablet is crushed then there will be more number of particles available for reaction. Hence, more number of collisions will take place due to which rate of reaction increases.

Using many antacid tables will also increase the number of molecules due to which there will be more collisions. Hence, more will be it's rate of reaction.

A catalyst is defined as a substance which helps in increasing the rate of a reaction without itself getting consumed in the reaction.

Therefore, adding catalyst to the water will also increase the rate of reaction.

When water is cooled during the reaction then kinetic energy between molecules decreases due to which there will be less number of collisions. Hence, rate of reaction will decrease.

Adding food coloring will have no effect on the rate of reaction as it is only changing the color of solution and does not participate in the chemical reaction.

Thus, we can conclude that given factors are matched to the effect it would have on the reaction rate are as follows.

- Crushing the antacid tablet

- Using many antacid tables

- Adding a catalyst to the water

- Cooling the water during the reaction

- Adding food coloring to the water

a corroding iron, if that's one of your choices
