For the following cell,
Zn(s)|ZnSO4(aq)||CuSO4(aq)|Cu(s)
when the concentration ofZn2+is 10 times the concentration ofCu2+,
the expression forΔG(in J  mol −1 ) is
[F is Faraday constant; R is gas constant; T is temperature; E°(cell) = 1.1 V]

Options:

Answer:
C
Solution:

ΔG = ΔG° + 2.303 RT  log 10 Q; Q =  Zn 2+ Cu 2−
= −2F 1.1  + 2.303 RT  log 10 10
= 2.303 RT−2.2 F
