• # question_answer A hypothetical electrochemical cell is shown below$\overset{O-}{\mathop{A}}\,|{{A}^{+}}(xM)||{{B}^{+}}(yM)|\overset{O-}{\mathop{B}}\,$The emf measured is + 0.20 V. The cell reaction is A)  The cell reaction cannot be predictedB) $A+{{B}^{+}}\xrightarrow{{}}{{A}^{+}}+B$C) ${{A}^{+}}+B\xrightarrow{{}}A+{{B}^{+}}$D) ${{A}^{+}}+{{e}^{-}}\xrightarrow{{}}A;{{B}^{+}}+{{e}^{-}}\xrightarrow{{}}B$

Solution :

${{E}_{cell}}=+ve$ thus redox changes are $A\xrightarrow{{}}{{A}^{+}}+{{e}^{-}}\,LHS$shows oxidation. ${{B}^{+}}+e\xrightarrow{{}}B\,RHS$shows reduction $A+{{B}^{+}}\xrightarrow{{}}{{A}^{+}}+B$
