Solution:

Activation energy
$E_{1}\approxE_{II}\approxE_{V}\approxE_{VI}$
$E_{1 \left(f\right)}\approx\left(E_{1}\right)_{\left(\right. b \left.\right)}\approxE_{2 \left(\right. b \left.\right)}\approxE_{3 \left(f\right)}\approxE_{3 \left(b\right)}\approxE_{4 \left(f\right)}\approxE_{5 \left(f\right)}\approxE_{6 \left(b\right)}$
$E_{2 \left(f\right)}\approxE_{4 \left(b\right)}$ (slow steps so larger)
