एक विधुत रासायनिक सेल,
`Sn(s)|Sn^(2+)(aq,1M)||Pb^(2+)(aq,1M)|Pb(s)` के लिए `([Sn^(2+)])/([Pb^(2+)])` का अनुपात क्या होगा, जब यह सेल साम्यावस्था प्राप्त करता है:
(दिया गया है: `E_(Sn^(2+)|Sn)^(0)=-0.14V,E_(Pb^(2+)|Pb)^(0)=-0.13V,(2.303RT)/(F)=0.006`)

A

`4.3`

B

1

C

`-2.15`

D

`2.14`

Text Solution

Verified by Experts

The correct Answer is:
D

साम्यावस्था पर
`E_("सेल")=0`
`E_("सेल")^(0)=-0.01V`
`Sn+Pb^(2+)toSn^(2+)+Pb`
`E_("सेल")=E_("सेल")-(0.06)/(2)"log"([Sn^(2+)])/([Pb^(2+)])`
`0.01=(0.06)/(2)"log"([Sn^(2+)])/([Pb^(2+)])`
`(1)/(3)="log"([Sn^(2+)])/([Pb^(2+)])`
`([Sn^(2+)])/([Pb^(2+)])=10^(1/3)=2.14`
