WebMar 9, 2024 · Re: Favoring reactions. Using the equation deltaG=-nfE (naught), if E (naught) is calculated using E (cathode)-E (anode), and E anode is bigger, this means that the total cell potential will be negative. Since negative times negative is positive, delta G is positive, which tells us that the forward reaction is not favored, but rather the reverse.
