For a particular reaction \( \Delta \mathrm{H}^{\circ}=-76.6 \mathrm{~kJ} \) and \( \Delta \mathrm{S}^{\circ}=226 \mathrm{~J} \mathrm{~K}^{-1} \). This reaction is:
(a) Spontaneous at all temperatures.
- (b) Non spontaneous at all temperatures.
(c) Spontaneous at temperature below \( 66^{\circ} \mathrm{C} \).
(d) Spontaneous at temperature above \( 66^{\circ} \mathrm{C} \).
