  • A
    $\Delta H \lt 0 ; \Delta S \lt 0$
  • B
    $\Delta H\gt0 ; \Delta S \lt 0$
  • Correct answer
    C
    $\Delta H \lt 0 ; \Delta S\gt0$
  • D
    $\Delta H\gt0 ; \Delta S\gt0$

Solution

$\Delta H \lt 0$ and $\Delta S\gt0$ are always favourable conditions for spontaneity at all temperatures.

Hence, the correct answer is option: 'C'.
