For the electrochemicl cell, `M|M^(+)||X^(-)|X E_((M^(+)//M))^(@) = 0.44 V` and `E_((X//X^(-)))^(@) = 0.33 V`
From this data one can deduce that :

A

`M +X rarr M^(+) +X^(-)` is the spontaneous reaction

B

`M^(+) +X^(-) rarr M +X` is the spontaneous reaction

C

`E_(cell) = 0.77V`

D

`E_(cell) = - 0.77V`

Text Solution

Verified by Experts

The correct Answer is:
B
For reaction (B)
`E_("cell")^(@)` values is positive hence it is spontaneous.
