the corrosion of iron is similar to the reactions that occur in an electrochemical cell. Oxidation and reduction occur at separate places on the metal and the circuit is completed by an electrolyte in solution one possible corrosion is Fe(s)+O2(g) + H2O(l) --> Fe^2+(aq) + OH-(aq)
a. identify the substances oxidized and the substance reduced?

b. using the half reactions write the balanced redox equation

c. prove the reaction is spontaneous at standard conditions
