a. Draw an enthalpy cycle to calculate H r for the reaction 2Al(s) + Fe 2
Question:
a. Draw an enthalpy cycle to calculate ΔHϴr for the reaction 2Al(s) + Fe2O3(s) → 2Fe(s) + Al2O3(s)
b. Calculate ΔHϴr using the following information:
ΔHϴf [Fe2O3(s)] = –824.2 kJ mol–1
ΔHϴf [Al2O3(s)] = –1675.7 kJ mol–1
