Calculate the e.m.f. of the cell in which the following reaction takes place.
`Ni_((s)) + 2Ag_((0.002M))^(+) to Ni_((0.160M))^(2+) + 2Ag_((s)) , "Given " E_("cell")^@ = 1.05 V `

Text Solution

Verified by Experts

`E_("cell") = E_("cell")^(0) = (0.059)/(2) log""([N_(1)^(2+)])/([Ag^(+)])`
`E_("cell") = 1.05 = (0.059)/(2)log""(0.16)/((0.002)^(2))`
`E_("cell") = 1.05 - 5.6021 = 0.774V`
