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

` 2.14` volt

B

` 1. 80` volt

C

` 1.07` volt

D

`0.82` volt

Text Solution

Verified by Experts

The correct Answer is:
C
`E=E^@ -(0.059)/n log.([Zn^(++)])/([Cu^(+)])=1.10 - (0.059)/2 log 1/(0.1)`
` =1.10 - 0.0295 log 10`
` 1.07` volt.

For the redox reaction: Zn(s) +Cu^(2+) (0.1M) rarr Zn^(2+) (1M)+Cu(s) taking place in a cell, E_(cell)^(@) is 1.10 volt. E_(cell) for the cell will be (2.303 (RT)/(F) = 0l.0591)

Consider the following reaction, Zn(s)+Cu^(2+) (0.1 M) rarr Zn^(2+) (1 M)+Cu(s) above reaction, taking place in a cell, E_("cell")^(@) is 1.10 V. E_("cell") for the cell will be (2.303 (RT)/(F)=0.0591)
