1.	In the conversion of limestone to lime: CaCO3(s)→CaO(s)+CO2(g) The values of △H∘ and △S∘ are 179.1 kJ mol−1 and 160.2 JK−1 respectively at 298 K and 1 bar. Assuming △H∘ and △S∘ remains constant with temperature, at which temperature conversion of limestone to lime will be spontaneous:
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 $K^{- 1}$ respectively at 298 K and 1 bar. Assuming $△ H^{\circ}$ and $△ S^{\circ}$ remains constant with temperature, at which temperature conversion of limestone to lime will be spontaneous:
