For the electrochemical cell, (M|M^(o+))...

For the electrochemical cell, `(M|M^(o+))||(X^(c-)|X)`, `E^(c-)._((M^(o+)|M))=0.44V`, and `E^(c-)._((X|X^(c-))=-0.33V`.
From this data, one can conclude that

A

`M+X rarr M^(o+)+X^(c-)` is a spontaneous reaction

B

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

C

`E^(c-)._(cell)=0.77V`

D

`E^(c-)._(cell)=-0.77V`

Text Solution

Verified by Experts

The correct Answer is:
b,c
`E^(c-)._(cell)=0.44-(-0.33)=0.77V`
Spontaneous reaction `:M^(o+)+X^(c-)rarr M+X`
