`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)gtC_(2)`

C

`C_(2)gtC_(1)`

D

none

Text Solution

Verified by Experts

The correct Answer is:
C
`ZntoZn_((c_(1)))^(2+)+2e^(-)`
`Zn_((c_(2)))^(2+)+2e^(-)toZn`
`Zn_((c_(2)))^(2+)hArrZn_((c_(1)))^(2+)`
`E=0-(0.0591)/(2)log((C_(1))/(C_(2)))`
`Eto+ve` when `C_(1)ltC_(2)`
