Answer» In the conversion of limestone to lime: $C a C O_{3} (s) \to C a O (s) + C O_{2} (g)$ The values of $△ H^{\circ}$ and $△ S^{\circ}$ are 179.1 kJ $m o l^{- 1}$ and 160.2 J/K respectively at 298 K and 1 bar. Assuming $△ H^{\circ}$ and $△ S^{\circ}$ remains constant with temperature, at what temperature will the conversion of limestone to lime be spontaneous?
