A Galvanic Cell is given. Write its Anode and Cathode half reactions, complete cell reaction and thus determine if the given is concentration cell.

[itex]Pt|O_2(1\; atm)|NaO\! H(10^{-3}M)||H_2SO_4(0.5M)|O_2(1\;atm)|Pt[/itex]

I know that at anode, Oxygen will get oxidised, maybe from NaOH solution and at cathode, Oxygen will get reduced.

Here's what I think of anodic reaction
[itex]2O\!H^-\rightarrow 2H^++O_2+4e^-[/itex]

And the mighty cathodic reaction
[itex]O_2+4e^-+2H^+\rightarrow 2O\!H^-[/itex]

And thus, this cell is just a concentration cell (i.e. E°(cell) = 0)


Am... I right??? :uhh:

Hello...??? Can please anyone answer the question that I am right with my guesswork??? This question is eating me inside out.
