1 Calculate the standard free energy change for the fol-
lowing reactions using the standard cell potentials for the
half-reactions that are involved:
(a) Fe(s) + Hg;*(aq) → Fe²*(aq) + 2 Hg(€)
(b) Fe*(aq) + Ag(s) + Cl¯(aq) → Fe²*(aq) + AgCl(s)
(c) 2 MnO4 (aq) + 5 Zn(s) + 16 H;O*(aq) →
2 Mn²*(aq) + 5 Zn²*(aq) + 24 H;O(€)
