For a reaction `A(s)+2B^(o+) rarr A^(2+)+2B`
`K_(c)` has been found to be `10^(12)`. The `E^(c-)._(cell)` is

A

`0.354V`

B

`0.708V`

C

`0.0098V`

D

`1.36V`

Text Solution

Verified by Experts

The correct Answer is:
a
`E=E^(c-)-(0.059)/(2) log K`
At equilibrium, `E=0`
`E^(c-)=(0.059)/(2) log K =(0.059)/(2) log 10^(12)`
`=(0.059)/(2)xx12=0.354`
