A hyptherical electrochemical cell is given as `A^(Ө)|A^+ (xM) || B^+ (yM) | B^(Ө)` The emf masured is `+ 0. 20 V`. The cell reaction is .A. `A + B^(+) rarr A^(+) + B`B. `A^(+) + B rarr A + B^(+)`C. `A^(+) + e rarr A, + B^(+) + e rarr B`D. cannot be predicted

Answer» Correct Answer - A
`E_("cell") = +ve`, then
`{:(ArarrA^(+)+e),(B^(+)+erarrB):}/(A+B^(+)rarrA^(+)+B)`
