In conversion of limestone to lime, CaCO_(3)(s) to CaO(s) + CO_(2)(g) the values of DeltaH^(@) and DeltaS^(@) are + 179.1 kJ mol^(-1) and 160.2 J/K respectively at 298 K and 1 bar. Assuming that DeltaH^(@) and DeltaS^(@) do not change with temperature, the temperature above which conversion of limestone to lime will be spontaneous is:

1.	In conversion of limestone to lime, CaCO_(3)(s) to CaO(s) + CO_(2)(g) the values of DeltaH^(@) and DeltaS^(@) are + 179.1 kJ mol^(-1) and 160.2 J/K respectively at 298 K and 1 bar. Assuming that DeltaH^(@) and DeltaS^(@) do not change with temperature, the temperature above which conversion of limestone to lime will be spontaneous is:
Answer» 1200 K 845 K 1118 K 1008 K Solution :`T = (DeltaH^(@))/(DELTAS^(@)) = (179.1 xx 10^(3)J)/(160.0JK^(-1))` ` = 1117.97 = 1118 K`
