How does a catalyst work?

by increasing the temperature of a chemical reaction

by decreasing the pressure of a chemical reaction

by increasing the concentration of reactants in a reaction

by decreasing the activation energy of a reaction

Verified Answer :

by decreasing the activation energy of a reaction

Catalysts work by decreasing the activation energy of a reaction. So, it's D.

What are catalysts?

Catalysts may be defined as any chemical substances that speed up the rate of chemical reactions by decreasing their activation energy without being devoured.

Catalysts usually lower the activation energy which leads to enhancing the rate of chemical reactions.

Therefore, it is well described above.
