MCQ
The correct thermodynamic conditions for the spontaneous reaction at all temperatures is
- A$\Delta H > 0$ and $\Delta S < 0$
- B$\Delta H < 0$ and $\Delta S < 0$
- C$\Delta H < 0$ and $\Delta S = 0$
- ✓$\Delta H < 0$ and $\Delta S > 0$
✓
Answer
Correct option: D.
$\Delta H < 0$ and $\Delta S > 0$
d
$\Delta G=\Delta H-T \Delta S$
$\Delta G=\Delta H-T \Delta S$
For spontaneous process
$\Delta S=+v e$
$\Delta H=-v e$
