Marcus electron-transfer parabolic-exponent framework: log k ∝ −(ΔG+λ)²/(4λRT) (inverted region witness)

Layer 2 — Chemistryin the electrocatalysis subtree

Marcus electron-transfer theory parabolic free-energy relationship: log k_ET ∝ −(ΔG + λ)²/(4·λ·R·T), where λ is the reorganization energy and ΔG the driving force. The exponent is a downward parabola in ΔG with maximum at ΔG = −λ (the…
