Fe3+ (aq) + 3e– → Fe (s)   Eored = +0.771 V

Based on its reduction potential, will aqueous iron (III) get oxidized or reduced? Why?

Reduced

Positive reduction potential

A voltaic cell is created based on the reaction:

Mg+2(aq) + Cu (s) --> Mg (s) + Cu2+ (aq) 

The Eocell = -3.14 V

Will this cell work? Why or why not?

The cell does not work. The standard cell potential is negative.  

If you applied a voltage greater than 3.14 V using a battery you could force the reaction to work (via electrolysis).

If Eocell is a positive voltage, what does that tell you about a reaction?

It is spontaneous and will run on its own.
