Multiple Choice
Consider the Daniell cell where the cell reaction and standard potential are:Zn(s) + Cu2+ (aq) Zn2+ (aq) + Cu (s) E° = 1.10 VIf the cell is initially at standard conditions ([Cu2+] = [Zn2+] = 1.00 M) , what are the concentrations of Cu2+ and Zn2+ when the cell potential has fallen to 1.06 V?If needed, use the following equation: G° = -nFE°, E° , E = E° -
, moles e- =
(If needed, refer to Table 17-1in the text)
A) [Cu2+]= 8.5 x 10-2 M; [Zn2+]=1.91 M
B) [Cu2+]= 0.94 M; [Zn2+]= 1.06 M
C) [Cu2+]= 1.91 M; [Zn2+]=8.5 x 10-2 M
D) [Cu2+]= 0.50 M; [Zn2+]=1.50 M
E) [Cu2+]= 0.90 M; [Zn2+]=1.10 M
