For the reaction 2 A (s) + B^(2+) (aq) to 2 A^(+) (aq) + B(s) , Nernst equation for the EMF of the cell is

Answer»

`E = E^(@) - (RT)/(2F) "ln" ([A^(+)])/([B^(2+)])`
`E = E^(@) - (RT)/(2F) "ln" ([A^(+)])/([B^(2+)]^(2))`
`E = E^(@) - (RT)/(F) "ln" ([A^(+)])/(SQRT([B^(2+)]))`
`E = E^(@) +(RT)/(F) "ln" ([A^(+)])/(sqrt([B^(2+)]))`

Solution :`E = E^(@) - (RT)/(2F) "ln" ([A^(+)]^(2+))/([B^(2+)]) = E^(@) - (RT)/(F) "ln" ([A^(+)])/(sqrt([B^(2+)]))`
