Explain why there was no corrosion on this nail from an equilibrium perspective

Recall that in Module 3 Lesson 4, you observed that very little corrosion occurred on the nail immersed in NaOH(aq) solution.  This observation is difficult to explain from an electrochemistry perspective since electrochemistry principles predict a spontaneous reaction that should cause corrosion.  Explain why there was no corrosion on this nail from an equilibrium perspective using the half-reaction shown below:

                           O2(g)  +  2 H2O(l)  +  4 e-    4 OH-(aq)

I've already seen someones answer to this on yahoo. can someone please give me an answer from the equilibrium point of view?
