You notice that a chemical reaction in your system is happening at a slow rate. you want to speed up the reaction. what do you do?

The correct answer is by adding an enzyme.

The explanation:

-when we increase the enzyme concentration, the maximum reaction rate highly increases.

-Conclusions: The rate of a chemical reaction increases as the substrate concentration increases.

- Enzymes can greatly and highly speed up the reaction rate. However, enzymes become saturated when the substrate concentration is high and great.

Add a catalyst to the reaction
