c. reactant.
b. coefficient.
d. catalyst.

Catalyst

Explanation:

To answer the following question we need to ask ourselves the following questions;

What is a catalyst?

A catalyst is any substance that increases the rate at which a chemical reaction occurs.

How does it perform its function?

Catalysts increase the rate of chemical reaction without be consumed.They do so by reducing the amount of activation energy of the reactants. By so doing the rate of formation of products increases.

Do catalysts undergo any change after the reaction?

Catalysts do not undergo permanent changes during the reaction. They remain the same at the end of the reaction/

3x + 2x = both people using the same measure of like 5x = x= 25 meters per second. 25ms. it takes them 4 seconds to
