Problem
A galvanic cell is assembled at 298 K using the following half-reactions.
Cu²⁺ + 2 e⁻ → Cu(s) E° = +0.34 V
Zn²⁺ + 2 e⁻ → Zn(s) E° = –0.76 V
The measured cell potential is 1.05 V when [Cu²⁺] = 1.0 M. Which statement about the concentration of Zn²⁺ in the Zn²⁺/Zn half-cell is most consistent with this measurement?
(a) [Zn2+] is less than 1.0M.},{
(b) [Zn2+] is greater than 1.0M.},{
(c) Changing [Zn2+] cannot influence the cell potential.
(d) [Zn2+] is exactly 1.0M.}],
