Which statement is reue in regard to a spontaneous redox reaction ?

A

`E_(red)^@` is always negative

B

`E_(cell)^@` is always positive

C

`E_(OX)^@` is always positive

D

`E_(cell)^@` is always negative

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaG^@ =- nFE^@ cell` if `E_(cell)^@` is positive, then `Delta G^@` will be `-ve` showing htat cell reaction is spontaneous.
