The standard redox potential (AE) for a redox reaction involving the transfer of two electrons is +0.32 V. What is the standard free energy change (AG") for this reaction? (Assume the Faraday constant is 100 kJ mol- V-, and that the reaction is taking place under standard conditions: pH 7 and 25C.) Select one alternative: O +6.4 kJ mol-1 O -64 kJ mol-1 +64 kJ mol-1 O -32 kJ mol-1
