A g |A g+ | A g l| A g E textcell=EA g / A g+°+EI- / A g I(s) A g° =−0.799−0.151=−0.950 V

Q. The standard cell potential for the electrochemical cell $A g / A g^{+} ∥ A g I / A g; E_{I^{-}}^{\circ} A g I (s) A g = - 0.151 V, E_{A g^{+} / A g}^{\circ} = 0.799 V$

$+ 0.950 V$

$- 0.950 V$

$- 0.648 V$

$+ 0.648 V$

$A g ∣ A g^{+} ∥ A g l ∣ A g$
$E_{cell} = E_{A g / A g^{+}}^{\circ} + E_{I^{-} / A g I (s) A g}^{\circ}$
$= - 0.799 - 0.151 = - 0.950 V$

Q. The standard cell potential for the electrochemical cell Ag/Ag+∥AgI/Ag;EI−∘​AgI(s)Ag=−0.151V,EAg+/Ag∘​=0.799V

+0.950V

−0.950V
