Unformatted text preview: r*, although we did not evaluate what that might be. Using the equation for G (the free energy) given in your notes, derive the correct relationship for r* in terms of G v (the volume free energy) and (the surface energy). Hint: this requires taking a derivative. Answer Selected Answer: r* = -2 / G Correct Answer: r* = -2 / G Response Feedback: Correct Take derivative with respect to respect to r, set equal to zero, and sove for r. Your basically finding where the slope equals zero on the G vs r curve....
