Question

8) Using a table of standard electrode potentials, predict whether the following reactions will be spontaneous, and calculate Eo for the reaction

a) Fe3+ (aq) + I- (aq) → Fe2+ (aq) + I2 (s)

b) Cl- (aq) + 2H2O → Cl2 (g) + H2 (g) + 2OH- (aq)

c) Ag (s) + H+(aq) + NO3-(aq) → Ag+ (aq)

potential (V)	reduction half- reaction
+2.87	F2(g) + 2 e- = 2F-(aq)
+1.33	Cr2 O7 2-(aq) + 14 H+(aq) + 6 e- = 2 Cr3+(aq) + 7 H2O(I)
+0.77	Fe3+(aq) + e- = Fe2+(aq)
+0.68	O2(g) + 2H+(aq) + 2 e- = H2O2(aq)
0	2 H+(aq) + 2 e- = H2(g)
-0.44	Fe2+ (aq) + 2 e- = Fe(s)
-0.83	2 H2O (I) + 2 e- = H2(g) + 2 OH-(aq)
-2.71	Na+ (aq) + e- = Na(s)
-3.05	Li+(aq) + e- = Li (s)
