If the temperature coefficient `((delE)/(delT))` is zero for a cell reaction then out of `DeltaS, DeltaH`, and `DeltaG` , the `…………………..` is zero.

Answer

`(DeltaS)`

Explanation

`(DeltaS)`
`DeltaS=nF((dE)/(dT))_(P)`
`DeltaS prop ((dE)/(dT))_(P)`
So when `((dE)/(dT))_(P)=0,DeltaS=0`
`DeltaH=-nF[E_(cell)T((dE)/(dT))_(P),SoDeltaHcancel(=)0`
`DeltaG=DeltaH-T DeltaS, ` iF `DeltaS=0,DeltaG=DeltaH cancel(=)0`
