A) 1.425
B) - 0.0843
C) 0.0843
D) 1.366
Correct Answer: C
Solution :
\[K\xrightarrow{\,}\,K_{Ex}^{+}+{{e}^{-}}\] \[\begin{align} & \,\,\underline{K_{In}^{+}+{{e}^{-}}\xrightarrow{\,}\,K} \\ & \,\,\underline{K_{In}^{+}\xrightarrow{\,}K_{Ex}^{+}} \\ \end{align}\] \[E={{E}^{o}}-\frac{0.0591}{1}\log \,\frac{{{[{{K}^{+}}]}_{Ex}}}{{{[{{K}^{+}}]}_{In}}}\] \[=0-0.0591\,\,\log \,\frac{15}{400}=0.0843\,V\]You need to login to perform this action.
