Question
For the oxidation of iron to form iron(III) oxide:
4Fe(s) + 302(g)→ 2FE2O3(s)
ASO = -549.73 JK1 at 298 K.
The enthalpy of formation of Fe203(s) is –824.2 kJ mol. What is the standard change in Gibbs free energy for this reaction at 298 K?
Item equation/constant:
AG° = AHO – TASS
O -660.4 kJ
O -988.0 kJ
O -1484.6 kJ
O-1812.2 kJ
