Fortbcclcctrochcmical cell, `M |M^(+)||X^(-)|X,E ^(@)_(M^(4)//M)=0.44and E ^(@)_(X//X)=0.33V.` From this data one can deduce that

A

`M +Xto M ^(+)+X` is the spontaneous reaction

B

`M ^(+)+X to 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,` M^(+)+X^(-) to M+X, E+_(cell)^(@)=0.44 -0.33=0.11V`
is positive, hence reaction is spontaneous.
