Question

1. How does a catalyst work in speeding up a reaction?

a. It lowers the activation energy.

C. It creates more reactants.

b. It provides more energy.

d. It increases the temperature.

Answer

A. It lowers the activation energy

Explanation:

Catalysts speed up reactions by lowering the activation energy (Ea). Although it lowers the activation energy of the reaction, the catalyst does not affect the energy/enthalpy levels of the products and reactants.
