Question

which component is affected when a catalyst is added to a chemical reaction?
○ the amount of substrate
○ the activation energy
○ the amount of product
○ the concentration of reactants

Explanation:

A catalyst is a substance that speeds up a chemical reaction by lowering the activation energy. It does not affect the amount of substrate or product at equilibrium, nor does it change the concentration of reactants at equilibrium. It only affects the rate at which the reaction reaches equilibrium by providing an alternative reaction pathway with a lower activation - energy.

Answer:

the activation energy
