Like equilibrium constants. values are temperature dependent. At $\text{80°C}$. for the cell diagram shown is 0.18 V.

$\text{Pt }\left|{\text{ H}}_{\text{2}}\left(g\right)\right|\text{ HCl}\left(aq\right)\text{ ||AgCl(}s\text{)| Ag}\left(s\right)$

The corresponding cell reaction is:

${\text{H}}_{\text{2}}\text{(}g\text{)+2AgCl(}s\text{)}\underset{}{\rightleftarrows }\text{2Ag(}s{\text{)+2H}}^{\text{+}}\text{(}aq{\text{)+2Cl}}^{\text{-}}\text{(}aq\text{)}$

Calculate the equilibrium constant for this reaction at $\text{80°C}$.
