What is the different between standard reaction Gibbs free energy and and Gibbs free energy? How do we know when to use the standard cell potential for the equation for standard reaction Gibbs free energy?

Standard Gibbs Free Energy is the value of Gibbs Free Energy at standard conditions. It does not change as the reaction proceeds, which is nice because Gibbs Free Energy does. When calculating standard Gibbs Free Energy, use standard cell potential.
