A simple equation relates the standard free‑energy change, Δ G ∘ ′ , to the change in reduction potential, Δ E ′ 0 . Δ G ∘ ′ = − n F Δ E ′ 0 The n represents the number of transferred electrons, and F is the Faraday constant with a value of 96.48 kJ ⋅ mol − 1 ⋅ V − 1 . Use the standard reduction potentials provided to determine the standard free energy released by reducing O 2 with FADH 2 .
