Using standard reduction potentials (Appendix E), calculate the standard emf for each of the following reactions: (a)

Question:

Using standard reduction potentials (Appendix E), calculate the standard emf for each of the following reactions:
(a) Cl2(g) + 2 I- (aq) → 2 Cl- (aq) + I2(s)
(b) Ni(s) + 2 Ce4+(aq) → Ni2+(aq) + 2 Ce3+(aq)
(c) Fe(s) + 2 Fe3+ (aq) → 3 Fe2+ (aq)
(d) 2 NO3- (aq) + 8 H+(aq) + 3 Cu(s) → 2 NO(g) + 4 H2O(l) + 3 Cu2+(aq)
