| Apologies if this thing is unnecessary:
High E values show tendency to be reduced (Fluorine). Low E values show tendency to be oxidized (Lithium).
The half reaction (if they are both forward) that is more negative is the one that will occur (in reverse) at the anode. Electrons will flow from the one you just selected to the opposite electrode which would be the cathode.
If that doesn't work note are you really asked to find direction of current or electron flow? Cause current goes cathode to anode for some braindead historical reason I believe...
It is also possible if it is from one of those cram books that a question was marked down wrong. |
