In an electrochemical cell `Delta G= Delta H`

A

`T rarr 0`

B

`T rarr oo`

C

`((d E_("cell"))/(dT))_(P) = 0`

D

`dE_("cell")= 0`

Text Solution

Verified by Experts

The correct Answer is:
A, C, D

`Delta G = Delta H rArr Delta S = 0 (or) T rarr 0`
`(Delta S)/(nF) = ((del E_("cell"))/(dT))_(P) rArr ((del E_("cell"))/(dT)) = 0 rArr del E_("cell") = 0`
