In conversion of limestone to lime,
CaCO3(s) → CaO(s) + CO2(g)
the values of ΔHo and ΔSo are + 179.1 kJ mol-1 and 160.2 J K-1 mol-1 respectively at 298 K and 1 bar. Assuming that ΔHo and ΔSo do not change with temperature, then calculate the temperature above which conversion of limestone to lime will be spontaneous.
- 1008 K
- 1200 K
- 845 K
- 1118 K
Answer
(D) 1118 K
