Question 1

For the reaction 3Fe(s) + C(s) Fe3C(s), ΔH° = 21 kJ/mol and ΔS° = 20.4 J/mol·K at 25°C.  Estimate the minimum temperature above which the formation of cementite (Fe3C) is favored.
◦ 1.0°C
◦ 970°C
◦ 700°C
◦ 1000°C
◦ 760°C

Question 2

How much energy (kJ) is released if 10.0g of Al(s) is reacted with excess Fe2O3(s) in the thermite reaction:  2Al(s) + Fe2O3(s) → Al2O3(s) + 2Fe(l)  ΔH° = - 822.8 kJ/mol
◦ 8,230 kJ
◦ 823 kJ
◦ 305 kJ
◦ 152 kJ
◦ 4,110 kJ
