Whatwill bethe emf for the given half cell Pt|H_(2)(P_(1)|H^(+)(aq)|H_(2)(P_(2))|Pt

Answer»

<P>`(RT)/(F)` in `(p_(1))/(p_(2))`
`(RT)/(2F)` in `(p_(1))/(p_(2))`
`(RT)/(F)` in `(P_(2))/(P_(1))`
NONEOF these

Solution :RHS `2H^(+)+2e^(-) RARR H_(2) +2e^(-)`
`KHS H_(2) (P_(1)) rarr 2H^(+)+2e^(-)`
overall reaction `H_(2) (p_(1)) rarr H_(2) (p_(2))`
`E=E^(@)-(RT)/(nF) "in" (P_(2))/(P+(1))=0 -(RT)/(2F)=(RT)/(2F) "in" (P_(1))/(p_(2))`
