Cell reaction is spontaneous when
Options
(a) ΔG⁰ is negative
(b) ΔG⁰ is positive
(c) ΔE⁰ Red is positive
(d) ΔE⁰Red is negetive
Correct Answer:
ΔG⁰ is negative
Explanation:
For a cell reaction to be spontaneous ΔG⁰ should be negative.
As ΔG⁰ = -nFE⁰, so the value will be -ve only when E⁰ is +ve.
n = no.of electrons involved, F = value of faraday’s constant.
