Using the stаndаrd electrоde reductiоn pоtentiаls given below, calculate the equilibrium constant at standard temperature and pressure for the following reaction: O2 (g) + 4 H+(aq) + 4 Fe2+ (aq) --> 4 Fe3+ (aq) + 2 H2O (l) O2 (g) + 4 H+(aq) + 4 e- (aq) --> 2 H2O (l) Eo red = + 1.23 V 4 Fe3+ (aq) + 4 e- (aq) --> 4 Fe2+ (aq) Eo red = + 0.77 V Ecell0=0.0592nlogK
