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

The cell raction cannot be prdicted

B

`1 A+B^+ rarr A^+ + B`

C

` A^+ +B rarr A+B^+`

D

` A^+ +e^- rarr A, V^+ e^(-) rarr B`

Text Solution

Verified by Experts

The correct Answer is:
B
`E_("cell") = + ve ` thus redox changes are
`A rarr A^+ =e^- LHS ` shows reductio .
`B^+ +e rarr` B RHS shows reduction
`A+B^+ rarr A^+ +B` .
