A hypothetical electrochemical cell shown below
`overset(" "o+)A|(xM) || B^(+)(yM)|overset(" "o+)B`
The e.m.f. measured is `+0.20" V "`. The cell reaction is :

A

`A^(+)+e^(-) to A , B^(+)+e^(-) to B`

B

The cell reaction cannot be predicted

C

`A^(+)+B^(+) to A^(+)+B`

D

`A^(+)+B^(+) to A+B^(+)`

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) The cell reaction is as follows :
`A to A^(+)+e^(-)`
`B^(+)+e^(-) to B`
`A+B^(+) to A^(+)+B`
