I have a question about gibbs free energy vs gibbs standard free energy. We know that at equilibrium deltaG = 0 and Q = K, and deltaG standard is a non-zero value. But I don't understand. If I want to see if a reaction is at equilibrium then I have to calculate the deltaG standard first, before I can calculate deltaG to see if its value is 0 or not. And everytime I do that, the deltaG standard equals 0...
