Ni2+ (aq) + Cd(8) ► Ni(s) + Cd2+ (aq) Ecoll = +0.15 V
Under standard conditions, a Ni-Cd galvanic cell generates a potential of +0.15 V using the chemical reaction represented above. Which of the following best explains how
(Ni2+] > 1 M affects the cell potential if this is the only change made to the operation of the galvanic cell?
A The ratio
CA
is smaller if Ni2+] > 1 M, resulting in Q < 1 and Ecell > E" cell
B
The ratio
Npr, is smaller if [Ni?+] > 1 M, resulting in Q >1 and Eclt > E" cells
С
The ratio
(NI
(C4"
is larger if (Ni?] > 1 M, resulting in Q > 1 and Ecell < E" cell
D
The ratio
IN
Cd?!
is larger if (Ni2+] > 1 M, resulting in Q < 1 and Ecell < Ecell
