What is the standard cell Potential$\left({\text{E}}_{\text{Cell}}^{\text{o}}\right)$for following cell reaction?
$\text{2Fe(s)}\text{+}{\text{O}}_{\text{2}}\text{(g)}\text{+}{\text{2H}}_{\text{2}}\text{O(l)}\rightleftharpoons {\text{2Fe}}^{\text{2+}}\text{(aq)}\text{+}{\text{4OH}}^{\text{-}}\text{(aq)}$

Given
${\text{E}}^{\text{o}}{}_{{\text{Fe}}^{\text{2+}}\text{(aq)}\text{|}\text{Fe}\text{=}-\text{0}\text{.44}\text{V}}$
${\text{E}}^{\text{o}}{}_{{\text{O}}_{\text{2}}\text{(g)}\text{|}{\text{H}}_{\text{2}}\text{O}\text{|}\text{OH}\text{=}\text{0}\text{.4}\text{V}}$
