Represent the cell in which the following reaction takes place
`Mg(s)+2Ag^(+)(0.0001M) to Mg^(2+) (0.130M)+2Ag(s)`
Calculates its `E_(cell)` if `E_("cell")^(Θ)=3.17V`

Text Solution

Verified by Experts

`E_("cell")` is written directly from `E_("cell")^(@)` as,
`E_("cell")=E_("cell")^(@) -("RT")/(2F) ln. ([Mg^(2+)])/([Ag^(+)]^(2))`
(or) `E_("cell")=3.17 - (0.059)/(2) log. (0.13)/((0.0001)^(2))`
`E_("cell")` of the given reaction `=3.17-0.21=2.96V`.
