separate redox reaction into its componet half-reactions

Post by nickname » Thu Nov 11, 2010 8:59 pm

I have to write the oxidation and reduction reactions for 3O2 + 4Fe---> 2Fe2O3

As the oxidation-half reaction I have 4Fe--->4Fe^3+ + 12 e-

As the reduction half reaction I have 3O2 + 12e- ---> 6O^2-

are my answers correct? Thank you!

apparently, your oxidative half-reaction could be substracted with 4 and the reductive half-reaction with 3...

Cis or trans? That's what matters.
