The equation CaCO3(s) CaO(s) + CO2(g) shows the decomposition of calcium carbonate. H = 178.3 kJ/mol, and S = 160.5 J/(molK). The free energy change for the reaction is 130.5 kJ/mol. Which correctly states the temperature at which the reaction took place and whether the reaction is spontaneous or nonspontaneous? Use G = H – TS.
