What is the difference between free energy of activation and activation energy?

Hi! The free activation energy refers to Gibbs free energy, which is often used to define the energy barriers of reactions, while the activation energy specifically refers to the amount of energy needed to get over an energy barrier. The activation energy is the difference between the transition state and the reactants.

activation energy: The minimum energy required for a reaction to occur. Free energy is a thermodynamic quantity equivalent to the capacity of a system to do work.
