Question 29 D
2 Ag(s) + Cu²+ (aq) → 2 Ag* (aq) + Cu(s)
Half-Reaction
Standard Reduction Potential, E° (V)
Ag* (aq) + e¯ → Ag(s)
+0.80
Cu?+ (aq) + 2 e → Cu(s)
+0.34
The reaction represented by the equation above serves as the basis for the construction of an electrochemical cell. The table gives the reduction half-reactions and their respective standard reduction
potentials. Based on the overall reaction, which type of electrochemical cell was constructed, and why?
A
A galvanic or voltaic cell, because the standard reduction potentials for the two half-reactions are positive and E cell = 0.80 + 0.34 = +1.14 V
A galvanic or voltaic cell, because the standard reduction potentials for the two half-reactions are positive and Ecel = 0.80 – 0.34 = +0.46 V.
96,500 x (-0.46)
An electrolytic cell, because AG =
= 44 kJ/mol and its operation requires a potential smaller than 0.46 V to be supplied.

2 x 96,500 x (-0.46)
An electrolytic cell, because AG =
89 kJ/mol and its operation requires a potential greater than 0.46 V to be supplied.
