In conversion of limestone to lime,
CaCO3(s) → CaO(s) + CO2(g)
the values of ΔH° and ΔS° are +179.1kJ mol–1 and 160.2J/K respectively at 298K and 1 bar. Assuming that ΔH° and ΔS° do not change with temperature, temperature above which conversion of limestone to lime will be spontaneous is
(a) 1118K
(b) 1008K
(c) 1200K
(d) 845K.
