For the redox change ,
`Zn_(s) + underset (0.1M)FuCu^2+ rarr underset(Zn^(2+))(1M) + Cu_((s))`,
Taking place in a cell ` E_(cell)^@ ` is ` 1.10` volt . `E_(cell) ` for the cell would be :

A

`1.07 V`

B

0

C

`0.82 V`

D

`2.14 V`

Text Solution

Verified by Experts

The correct Answer is:
A
`E = E_(cell)^(@) + (0.059)/(2)log'([Cu^(2+)])/([Zn^(2+)])`
`= 1.0 + (0.059)/(2)log'(0.1)/(1)`
`= 1.07 V`
