In which of the following redox reactions are neither the reactants nor the products favored ?A. ` Co(s) +Ni^(2+) (aq.)rarr Co^(2+) (aq.) + Ni(s)`B. ` Cu(s) +2Ag^(2+) (aq.) rarr Cu^(2+) (aq.) +2 Ag(s)`C. `Zn(s) +Cu^(2+) (aq.) rarr Zn^(2+) (aq.) + Cu(s)`D. ` Fe(s) +3Cu^(2+) (aq.) rarr 2Fe^(3+) (aq.) + Cu(s)` |
