### Winter 2011 Midterm #7&8 part C

In the Winter 2011 midterm, #7&8 part c asks what is Keq and the change in free energy at 25 degrees C. They use the equation logKeq=nE/0.0592V. Can someone explain to me how to get this formula?

that formula was derived from delta G= -RTlnK combined with delta G= -nFE, to find the value of K.
I found it easier to follow if I first found delta G, and then plugged that value in to solve for K.

Return to “Appications of the Nernst Equation (e.g., Concentration Cells, Non-Standard Cell Potentials, Calculating Equilibrium Constants and pH)”
