Question

Question 8 of 10 What effect does a catalyst have on the energy of a reaction system? A. It increases the initial energy of the reactants. B. It reduces the final energy of the products. C. It reduces the activation energy. D. It has no effect on the energy of a reaction system.​

Answer 1

Answer: It reduces the activation energy.

Step-by-step explanation:

A catalyst is a material that, without being consumed by the process, speeds up a chemical reaction or decreases the temperature or pressure required to initiate one. The addition of a catalyst to a reaction is known as catalysis.

The bonds holding together the atoms in molecules are ruptured, altered, and repaired during a chemical reaction, recombining the atoms to form new molecules. By decreasing the activation energy, the energy hurdle that must be cleared for a chemical reaction to take place, catalysts improve the efficiency of this process. As a result, catalysts facilitate the formation of chemical bonds between atoms to create novel combinations and new compounds. Chemical processes are accelerated and become more energy-efficient when catalysts are used.
