Emf of the following cell at 298 K in V is x × 10^-2.

$Z n | Z n^{2 +} (0.1 M) | | A g^{+} (0.01 M) | A g$

The value of x is………… (Rounded off to the nearest integer)

$[G i v e n : E_{Z n^{2 +} / Z n}^{0} = - 0.76 V; E_{A g^{+} / A g}^{0} = + 0.80 V; \frac{2.303 R T}{F} = 0.059]$

${E^{o}}_{C e l l} = {E^{o}}_{A g^{+} / A g} - {E^{o}}_{Z n^{+ 2} / Z n} = 0.8 + 0.76 = 1.56 V$

Anode : $Z n (s) \to Z n^{2 +} (a q) + 2 e^{-}$

Cathode : 2Ag⁺(aq) + 2e^- -> 2Ag(s)

Zn(s) + 2Ag⁺(aq) -> Zn²⁺ (aq) + 2Ag(s)

$E_{c e l l} = {E^{o}}_{C e l l} - \frac{0.0591}{n} l o g \frac{[Z n^{2 +}]}{{[A g^{+}]}^{2}} = 1.56 - \frac{0.0591}{2} l o g (\frac{0.1}{1 0^{- 4}})$

x = 147
