For the cell $\mathrm{Cd}\left|\mathrm{CdCl}_{2} \| \mathrm{AgCl}\right| \mathrm{Ag} ; \mathrm{E}_{\text {cell }}^{\mathrm{o}}=0.675 \mathrm{V}$ and $\mathrm{dE}_{\text {cell }}^{\mathrm{o}} / \mathrm{dT}=-6.5 \times 10^{-4} \mathrm{VK}^{-1}$ at $27^{\circ} \mathrm{C}$. The $\Delta \mathrm{H}\left(\mathrm{kJ} \mathrm{mol}^{-1}\right)$ value for the reaction $\mathrm{Cd}+2 \mathrm{AgCl} \rightarrow 2 \mathrm{Ag}+\mathrm{CdCl}_{2}$ is closest to
