Re: What is Free Energy of Activation
The free energy of activation refers to the deltaG(Gibbs Free Energy) of the reaction.

Re: What is Free Energy of Activation
You can also think of it as energy difference between the transition state of a reaction and the ground state of the reactant or the difference between transition states and intermediates.
Re: What is Free Energy of Activation
Moreover, free energy of activation includes both the standard enthalpy of activation and the standard entropy of activation; thus, it is more accurate than the activation energy, which only accounts for the standard enthalpy of activation. Although both free energy of activation and activation energy have similar values, they are not exactly equal.

Re: What is Free Energy of Activation
When you say it includes both entropy and enthalpy are you saying that because when one calculates Gibbs free energy you use both in the equation? Would both of the values used be referring to the activation energy?

Re: What is Free Energy of Activation
In regards to gibbs free engery of activation, it will always be positive as energy is usually taken up for the reaction to happen.

Re: What is Free Energy of Activation
The free energy of activation is just the difference in energy between the transition and ground state in a reaction.

Hi! The free energy of activation of a reaction is the difference in energy between the transition and ground state.

Re: What is Free Energy of Activation
The difference in energy between the products and reactants. When energy is released, it is exothermic, when energy is added it is endothermic.

Re: What is Free Energy of Activation
The free energy of activation is the energy released during the activation reaction (Delta G)= Gibbs Free Energy.
