How do you derive the Nernst equation?

You should use the two equations for delta G and set them equal to each other. So set delta G = delta G(standard) + RTlnQ equal to delta G=-nFE

equation 1 del G = -rtlnK equation 2 del g = -nFe*

When you use the two delta G equations and set them equal to each other (deltaG = - RTln(K)) and (deltaG = -nFE), you can derive the Nernst equation

You set the two equations for delta G equal to each other since they both give delta G
