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

Respuesta :

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.
