1.

`Zn|Zn^(2+)(c_(1)) || Zn^(2+)(c_(2))|Zn`. For this cell `DeltaG` is negative if `:`A. `C_(1) = C_(2)`B. `C_(1) gt C_(2)`C. `C_(2) gt C_(1)`D. None of these

Answer» Correct Answer - C
`{:(ZnrarrZn_(C_(1))^(2+)+2e),(Zn_(C_(1))^(2+)+2erarrZn):}/(Zn_(C_(1))^(2+)rarrZn_(C_(1))^(2+))`
Thus `E_("cell") = +ve` only `c_(2) gt c_(1)` bacause
`E_("cell") = (0.059)/(2)"log"([Zn_(C_(2))^(2+)])/([Zn_(C_(1))^(2+)])`
