Given the following information, calculate the theoretically maximum number of moles of ATP that could be synthesized (from ADP and Pi) by the transfer of 2 moles of electrons from cytochrome b to c under standard conditions.

2 cyt c (Fe3+) + 2 e- --> 2 cyt c (Fe2+) = +0.255 V

2 cyt b (Fe3+) + 2 e- --> 2 cyt b (Fe2+) = +0.075 V

Faraday's constant kcal/V-electron. Standard free energy for ATP hydrolysis kcal/mole.
