Chemistry problem

Question

A voltaic cell will generate voltage if

the half-reactions and concentrations in each half-cell are identical

the redox reaction has a negative ΔG°

the half-reaction with the more negative E° is the oxidation half-reaction

Answer 1

the redox reaction has a negative ΔG° since this means the reaction is spontaneous.

(would have chosen "the half-reaction with the more negative E° is the oxidation half-reaction" if it said .. with the more negative standard reduction Eº)
