If acidic H2O2 is mixed with Fe^2+, which reaction occurs: theoxidation of Fe^2+ to Fe^3+ or the reduction of Fe^2+ to Fe? Givethe balanced redox reaction for each possibility and explain yourreason for selecting the reaction which will occur. Assume standardsolution concentrations.
For a) I have:
red: H2O2 + 2H+ + 2e- ---> 2 H2O E=+1.78 V
oxi Fe2+ ----> Fe3+ + e- E=-0.77V
Ecell = 1.01V
I'm stuck on b) but for the explanation I think I understandthat the one which is more positive is more thermodynamicallyfavoured, but if I'm wrong on this I'd appreciate a pointer in theright direction.
