Question

दी गई सेल `Pt-underset(P_(1))(H_(2))|H^(+)|underset(P_(2))(H_(2))-Pt` का विo वाo बल है
A. `(RT)/(F)"log"(P_(1))/(P_(2))`
B. `(RT)/(2F)"log"_(e)(P_(1))/(P_(2))`
C. `(RT)/(F)"log"_(e)(P_(2))/(P_(1))`
D. इनमे से कोई नहीं

Answer 1

`H_(2)to2H^(+)+2e`
`2H^(+)+2eunderset(P_(2))(toH_(2))`
`E_("cell")=E_(OP_(H))^(@)+E_(RP_(H))^(@)+(RT)/(2F)"log"_(e)([P_(H_(2))]_(1))/([P_(H_(2))]_(2))`
`=(RT)/(2F)"log"_(e)(P_(1))/(P_(2))`
