`25^(@)C` पर निम्नलिखित सेलो के विधुत वाहक बल ज्ञात करो ।
(a) `Fe|underset(0.3M)(Fe^(2+))||underset(0.1M)(Sn^(2+))|Cn`
(b) `Fe|underset(a=0.1)(FeSO_(4))||underset(1=0.01M)(CuSO_(4))|Cu`
(c ) `underset(2" atm")(Pt_(H_(2)))|HCl|underset(10"atm")(H_(2)(Pt))`
दिया है ,`E_(O.P._(H))^(@)=0.0V`,
`E_(O.P._((Fe//Fe^(2+))))^(@)=0.44V`
`E_(O.P._((Cu//Cu^(2+))))^(@)=-0.337V`,
`E_(O.P._((Sn//Sn^(2+))))^(@)=0.14V`

Answer

(a) 0.285 V (b) 0.7475 V (c) `-0.0206V`
