For the concentration cell Cu|Cu^(2+)(...

For the concentration cell
`Cu|Cu^(2+)(C_(1))||Cu^(2+)(C_(2))|Cu,DeltaG` will be negative if

A

`C_(1)=C_(2)`

B

`C_(1)gtC_(2)`

C

`C_(2)gtC_(1)`

D

None of these.

Text Solution

Verified by Experts

The correct Answer is:
C
A concentration cell (reversible w.r.t. cation) is spontaneous `(DeltaGlt 0"or" E_("cell"gt0)` if `C_(2)gtC_(1)`
`E_("cell")=(0.0591)/(2)"log"(C_(2))/(C_(1)))`
If `C_(2)gtC_(1).E_("cell")gt0`
