Cell reaction is spontaneous when
A
$$\Delta $$Go is negative
B
$$\Delta $$Go is positive
C
$$\Delta $$Eored is positive
D
$$\Delta $$Eored is negative
Explanation
For spontaneous reaction $$\Delta $$Go = – ve and
Eocell = + ve
as $$\Delta $$Go = – nFEocell
where, n = number of electrons taking part
Eo = emf of cell
F = Faraday constant
