Question
Using Eºcell, choose all the reactions that are nonspontaneous.
2Fe2+ (aq) + Cl2(g) → 2Fe3+,
2Al(s) + 3Zn²+ (aq)
-
(aq) + 2Cl(aq)
2A1³+ (aq) + 3Zn(s)
(aq)
Sn2+ (aq) + Pb2+
Zn2+ + Cu(s)→Cu2+ + Zn(s)
2Ag (aq) + Cu(s) → 2Ag(s) + Cu²+,
(aq)
2Cl2(g) + 2H₂O(1)→ 4HCl(aq) + O2(g)
(aq) → Pb(s) + Sn4+
