Homework Help: Chem AP

Cytochrome, a complicated molecule that we will represent as CyFe2+, reacts with the air we breathe to supply energy required to synthesize adenosine triphosphate (ATP). At pH 7.0 the following reduction potentials pertain to this oxidation of CyFe2+:

O2(g) + 4 H+(aq) + 4 e- --> 2 H2O(l);
E= +0.82 V

CyFe3+(aq) + e- --> CyFe2+(aq);
E= +0.22 V

a) What is delta G for the oxidation of CyFe2+ by air?

b) If the synthesis of 1.00 mol of ATP from (ADP) requires a delta G of 37.7 kJ, now many moles of ATP are synthesized per mole of O2.

I know for part a you have to add the two Es but after that I'm not sure
