Problem

The chemical reaction that causes chromium to corrode in air is given by:

4Cr + 3O2 → 2Cr2O3

In which

ΔH°rxn = -2256 kJ

ΔS°rxn = -549.1 J/K

At what temperature (Teq) do the forward and reverse corrosion reactions occur in equilibrium?

Express your answer as an integer and include the appropriate units.
