Calculate the standard cell potential in(V)

Question:

Calculate the standard cell potential in(V) of the cell in which following reaction takes place :

$\mathrm{Fe}^{2+}(\mathrm{aq})+\mathrm{Ag}^{+}(\mathrm{aq}) \rightarrow \mathrm{Fe}^{3+}(\mathrm{aq})+\mathrm{Ag}(\mathrm{s})$

Given that

$\mathrm{E}_{\mathrm{Ag}^{+} / \mathrm{Ag}}^{\mathrm{o}}=\mathrm{xV}$

$\mathrm{E}_{\mathrm{Fe}^{2+} / \mathrm{Fe}}^{\mathrm{o}}=\mathrm{yV}$

$\mathrm{E}_{\mathrm{Fe}^{3+} / \mathrm{Fe}}^{0}=\mathrm{ZV}$

  1. $x+2 y-3 z$

  2. $x-z$

  3. $x-y$

  4. $x+y-z$
