Default Gibbs Free Energy
What is the difference between ?G' and ?G'°? I know that these are both constant for a given reaction, and the book I'm using calls both of them standard free energy change. Is there a difference between the two? Is ?G'° only used when the pH is 7?

Default Re: Gibbs Free Energy
Delta G' is Gibbs free energy calculated at pH 7 at GIVEN conditions.
Delta G'° is Gibbs free energy calculated at pH 7 at STANDARD conditions, i.e. all reactants at concentration of 1M.
