Question

A voltaic cell will generate a voltage if

the half-reactions are identical, but the concentrations in the half cell are different.

the half-reaction with the more negative E° is the reduction half-reaction.

the redox reaction has a positive ΔG°

Answer 1

the half-reaction with the more negative E° is the reduction half-reaction.

(caveat: assuming that by Eº you are referring to reduction potential and not oxidation potential)
