Question

Calculate the useful work of the reaction $A g (s) + 1 / 2 C l_{2} (g) \to A g C l (s)$ .
Given $E_{c l_{2} / C l^{-}}^{0} = + 1.36 V,$ $E_{A g | A g C l | C l^{-}}^{0} = 0.22 V$ if $P_{C l_{2}} = 1 a t m$ and $T = 298 K$ .

Solution

The correct option is A 110 kJ/mol
(1) $A g C l (s) + e \to A g (s) + C l^{-}$ $E^{0} = 0.22 V$
(2) $1 / 2 C l_{2} + e \to C l^{-}$ $E^{0} = 1.36 V$
We get
$A g (s) + 1 / 2 C l_{2} (g) \to A g C l (s)$ $E_{c e l l}^{0} = 1.14 V$
$∴ Δ G = - n E F^{0} = - (1) (96500) (1.14) = - 110 k J / m o l$
