Question
You wish to construct an electrochemical cell from the following half-
reactions:
Ag" (aq) + e --> Ag (s)
E° = 0.80 V
Cd2+ (ag) + 2 e> Cd (s)
E° = -0.40 V
a.) What materials should the cathode and anode be constructed from?n
b.) Assume that [(Ag*] = 1.00 M and [Cd2+] = 1.00 M. Use this information to
%3D
%3D
construct an abbreviated cell diagram for the battery.
c.) Calculate the value of the standard cell potential, E°cell, for the battery.
d.) Calculate the standard free energy change, AG cel, for the battery.
F = 9.65 x 104 C/mol
e.) Calculate the non-standard cell-potential, Ecell, at 25°C when [Ag*] = 0.50
