Discuss the effect of temperature change on the spontaneity of the following reactions at 1 atm:

a. Al2O3 (s) + 2Fe (s) ----------2Al (s) + Fe2O3(s)

delta H =851.4 kJ; delta S = 38.5

b. N2H4 (l)-----------------N2 + 2H2 (g)

delta H = -50.6 kJ; delta S = 0.3315 kJ/K

c. SO3 (g) ---------------SO2 (g) + 1/2 O2 (g)

delta H = 98.9 kJ; delta S = 0.0939 kJ/K
