Question

For a spontaneous reaction the ΔG, equilibrium constant (K) and E°_cell will be respectively
(a) –ve, >1, +ve 

(b) +ve, >1, –ve

(c) –ve, <1, –ve 

(d) –ve, >1, –ve

Answer 1

(a) : For spontaneous process, ΔG = –ve
Now ΔG = –RT ln K
When K > 1, ΔG = –ve
Again ΔGº = – nFEº
When Eº = +ve, ΔGº = –ve
