The equation CaCO3(s) Right arrow. CaO(s) + CO2(g) shows the decomposition of calcium carbonate. Delta. H = 178.3 kJ/mol, and Delta. S = 160.5 J/ 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 Delta. G = Delta. H – TDelta. S.
0.30 K, spontaneous
1.92 K, spontaneous
297.8 K, nonspontaneous
1,924 K, nonspontaneous
