Question
Consider the following electrochemical cell at 298 K $\mathrm{Pt}\left|\mathrm{HSnO}_2^{-}(\mathrm{aq})\right| \mathrm{Sn}(\mathrm{OH})_6{ }^{2-}(\mathrm{aq})\left|\mathrm{OH}^{-}(\mathrm{aq})\right| \mathrm{Bi}_2 \mathrm{O}_3(\mathrm{~s}) \mid \mathrm{Bi}(\mathrm{s})$. If the reaction quotient at a given time is $10^6$, then the cell EMF ( $\mathrm{E}_{\text {cell }}$ ) is $\_\_\_\_$ $\times 10^{-1} \mathrm{~V}$ (Nearest integer). Given the standard half-cell reduction potential as $\mathrm{E}_{\mathrm{Bi}_2 \mathrm{O}_3 / \mathrm{Bi}_1 \mathrm{OH}^{-}}^{\circ}=-0.44 \mathrm{~V}^{\circ}$ and $\mathrm{E}_{\mathrm{Sn}(\mathrm{OH})_6^{\circ} / \mathrm{HSnO}_2^{-}, \mathrm{OH}^{-}}^{\circ}=-0.90 \mathrm{~V}$
