Give the electro-chemical reaction that represents the corrosion or rusting of iron.

Explanation

Reusting of iron: Iron converts itself into its oxixe `Fe_(2)O_(3)`
The electr4ochemical reaction that represents the correosion or rusting of iron is
Anod `: 2Fe_((s))to 2 Fe ^(2+)+4e^(-)" "E_((Fe^(2+)//Fe))^(0)=-0.44V`
Cathod `:O_(2(g))+4H_((aq))^(+)+4e^(-)to 2H_(2)O_((l))" "E_(H^(+)//O_(2)O)^(Θ)=1.23V`
Overall reaction : `2Fe_((s))+O_(2(g))+4H_((aq))^(+)to 2Fe_(aq)^(+2)+2H_(2)O_((l))E_((cell"))^(Θ)=1.67V`
