During Electron Transfer Through the Mitochondrial Respiratory Chain, the Overall $\rightarrow$

question 77

Essay

During electron transfer through the mitochondrial respiratory chain, the overall reaction is NADH + 1/2 O₂ + H⁺ $\rightarrow$ NAD⁺ + H₂O. The difference in reduction potentials for the two half-reactions ( $\Delta$ E'°) is +1.14 V. Show how you would calculate the standard free-energy change, $\Delta$ G'°, for the reaction as written above. (The Faraday constant, , is 96.48 kJ/V · mol.)
