I have to find delta G from a problem.
Not the standard free energy, from the change in engery. So this delta G does not have the degree sign above.
The equation i used was deltaG=standard G+RTlnQ
If deltaG was a positve number, what does that tell me.
I know that if the standard free energy is a positive number, it tells me that the reaction is not a product favored. So whats the difference between standard free energy and the change in free energy.
If I understand the question, the standard free energy, delta G^o, is the free energy of formation from the elements at 25 C. The free energy of a reaction is the free energy of the products minus the free energy of the reactants.
