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
