How do catalysts increase reaction rates? *
By increasing the activation energy.
By broadening the energy barrier.
By forming an activated complex with lower energy.
By changing the net thermodynamics of the reaction.

Answer :

Answer:

By forming an activated complex with lower energy.

Explanation:

When catalyst is added to a reaction , it forms  an activated catalyst which has lower activation energy . So initiation of reaction requires less energy and reaction becomes fast .

Hence third option is correct.
