Free Energy of Activation

[Eden Breslauer-Friedman 2A]

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

Thanks!

I think that they might refer to the same thing, because activation energy technically is the amount of free energy that needs to be put into a system in order allow it to transition from one state to another.

Based on what I've seen in a previous forum post, the free energy of activation takes entropy and enthalpy into account because it directly refers to the concept of free energy. Activation energy itself, on the other hand, only takes enthalpy into account.

Energy must be added to the reactants to overcome the energy barrier, which is recovered when products are formed. The energy barrier is Ea, the activation energy. The activation energy is different from the ΔG, which is the free energy difference between the reactants and products.

This was really helpful.

Thank you

Hi! I believe that free energy of activation is the amount of energy available whereas activation energy is the amount of free energy needed to go from the energy level of reactants to the energy level of products.
