Not understanding this. These are two unrelated reactions.

This is the explanation from TBR (well, the equation are actually examples of this situation mentioned by TBR).

Balancing redox reactions is easy when you follow the procedure justo utlined in the previous section. However, there are a few pitfalls of which you should be aware. They involve compounds with multiple atoms undergoing oxidation or reduction. The following reactions are examples of reduction half-reactions iwht multiple atoms within a molecule being reduced

Cr2O7 2- +6e- ---> Cr2O3

H2O2 + +2e- ---> 2 OH-

Could they be talking about disproportionation? Those examples don't really show it, but that's all I can think of. Otherwise it doesn't make any sense to me either.

confused by this. anyone understand "multiple redox sites"?

Wow.. I really came a long way in my MCAT prep.

Broski, didn't you get a 33 on your MCAT?
