For the following cell,
`Zn(s)|ZnSO_(4)(aq)||CuSO_(4)(aq)||Cu(s)`
When the concentration of `Zn^(2+)` is 10 times the concentration of `Cu^(2+)`, the expression for `DeltaG`
(in J `"mol"^(-1)`)
[F is Faraday constant, R is gas constant] T is temperaure, `E^(@)("cell")=1.1V`
A. 2.303 RT +1.1 F
B. 1.1 F
C. 2.303 RT -2.2 F
D. `-2.2 F`

Correct Answer - C
(c ) `DeltaG=DeltaG^(@)+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"`
