At LHS (oxidation) 2 ×( Ag longrightarrow Ag ++e-) E ox -=-x At RHS (reduction) Cu 2++2 e- longrightarrow Cu E°red = + y 2Ag + Cu2+ to Cu + 2Ag+ , E°red = (y - x) Note: E° values remain constant when half-cell equation is multipled/divided.

Q. For a cell given below :

$A g ∣ A g^{+} ∣∣ C u^{2 +} ∣ C u$

$A g^{+} + e^{-} - \to A g + E^{\circ} = x$

$C u^{2 +} + 2 e^{-} \to, E^{\circ} = y$

$E^{\circ}$ cell is :

$x + 2 y$

$2 x + y$

$y - x$

$y - 2 x$

Q. For a cell given below : Ag∣Ag+∣∣Cu2+∣Cu Ag++e−−​→Ag+​E∘=x Cu2++2e−→,E∘=y E∘ cell is :

x+2y

2x+y

y−x

y−2x

At LHS (oxidation) 2×(Ag⟶Ag++e−) Eox−​=−x At RHS (reduction) Cu2++2e−⟶Cu Ered∘​=+y __________________________________ 2Ag+Cu2+toCu+2Ag+,Ered∘​=(y−x) ___________________________________ Note : E∘ values remain constant when half-cell equation is multipled/divided.

Q. For a cell given below :
