Marcus inverted-region maximum: d(dG^dagger)/d(dG) = 0 at dG = -lambda; dG^dagger_min = 0

Marcus inverted-region maximum rate theorem. From framework F8, the activation free energy is delta-G^{dagger}(delta-G) = (delta-G + lambda)^2 / (4*lambda), a parabola in delta-G with minimum at delta-G = -lambda. Setting the derivative to…
