NEETChemistryElectrochemistryMCQ+4 / −1
Cell reaction is spontaneous when
  1. A
    Δ\DeltaΔGo is negative
  2. B
    Δ\DeltaΔGo is positive
  3. C
    Δ\DeltaΔEored is positive
  4. D
    Δ\DeltaΔEored is negative
View written solutionFree

Correct answer: A

For spontaneous reaction Δ\Delta ΔGo = – ve and

Eocell = + ve

as Δ\Delta ΔGo = – nFEocell

where, n = number of electrons taking part

Eo = emf of cell

F = Faraday constant
