Calculate the number of moles of cytochrome c3+ (Fe3+) formed from cytochrome c2+ (Fe2+) with the Gibbs energy derived from the oxidation of 1 mole of glucose. There is no H+ involved in the reaction. Delta rGo= -2879kJ for the degradation of the 1 mole of glucose to CO2 and H2O. Use table from the lecture to determine Eo for the c3+/ c2+ couple.
