MCQ
For a spontaneous reaction the $\Delta G,$ equilibrium constant $ (K)$ and $E_{Cell}^o$ will be respectively
- ✓$ - ve,\, > 1,\, + ve$
- B$ + ve,\, > 1,\, - ve$
- C$ - ve,\, < 1,\, - ve$
- D$ - ve,\, > 1,\, - ve$
✓
Answer
Correct option: A.
$ - ve,\, > 1,\, + ve$
a
we know $\Delta G =- RT \ln K =- nF E ^{\circ}$
we know $\Delta G =- RT \ln K =- nF E ^{\circ}$
We know for a spontaneous reaction
$\Delta G \,<\,0 \text {. }$
$\therefore- RT \ln K \,<\,0$
$\therefore \ln K\,>\,0$
$\therefore K\,>\,1$
and $- nF E ^{\circ}<0$
$\therefore E _{\text {cell }}^{\circ}\,>\,0$
