How do catalysts affect a chemical reaction?
Provide activation energy
Increase activation energy
Lose activation energy
Lower activation energy
Catalysts lower the activation energy of a chemical reaction. Activation energy is the energy required for a reaction to start or proceed. By lowering the activation energy, catalysts make it easier for the reactants to overcome the energy barrier and initiate the reaction. This allows the reaction to occur more quickly or at lower temperatures than it would without a catalyst. In other words, catalysts provide an alternative reaction pathway with a lower activation energy, making the reaction more favorable.
Which answer is it
Catalysts lower the activation energy of a chemical reaction.
