Cell reactiomn is spontaneous when

A

`E_(red)^(@)` is negative

B

`E_(red)^(@)` is positive

C

`DeltaG^(@)` is negative

D

`DeltaG` is positive

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaG=Delta -TDeltaS`
For a spontaneous cell reaction `DeltaH` should be negatyive and `DeltaS` should be positive.
Hence, `DeltaG` should be negative.
