For the electrochemical cell having E^@(...

For the electrochemical cell having `E^@(M^+//M)` =0.44 V and `E^@(X//X)` =0.33 V . From this data, one can deduce that

A

`M+XtoM^+X^-` is the spontaneous reaction

B

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

C

`E_(cell)^@` =0.77 V

D

`E_(cell)^@` =-0.77 V`

Text Solution

Verified by Experts

The correct Answer is:
B
EMF for (b) is positive and = `E_(red)^@(M)+E_(OX)^@(X)`
`=0.44+(-0.33)=0.11` V
If EMF of a cell is positive, cell reaction will be spontaneous
