delta G vs. standard Gibbs free energy

Postby Virpal Gill 1B » Tue Feb 13, 2018 2:05 pm

I am confused on the use of and . I know that when is negative the reaction is spontaneous, but does this also apply to ? What is used for?

They're almost the same thing! ∆G° is just defined in terms of the standard molar Gibbs energies of the reactants and products; it's the difference in energy between the pure products and the pure reactants that won't change as the reaction proceeds.
