2Ca (s) + O2 (g) → 2CaO (s) 

ΔH°rxn = -1269.8 kJ; ΔS°rxn = - 364.6 J/K 

Part A

Calculate the free energy change for the reaction at 33°C. 

Express your answer using four significant figures.

Part B 

Is the reaction spontaneous? 

                                 (i) spontaneous 

                                 (ii) nonspontaneous
