Question

Difference between free energy and activation energy

Answer 1

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

Answer 2

Answer:

Activation energy

There is an energy barrier that separates the energy levels of the reactants and products. ... The energy barrier is known as Ea, the activation energy. The activation energy is distinct from the ΔG, or free energy difference between the reactants and products.
