The Gibbs free energy of the formation of one mole of pure TiO2 (s) from pure Ti (s) and pure oxygen gas is given as:
Ti (s) + O2 (g) = TiO2 (s) ΔG°TiO2 = -446230 + 88.9T J/mole
Discuss, based on calculations, whether Ti can be oxidized inside a heat-treatment furnace, which works at 1024 °C and 1 atm air (oxygen and nitrogen mixture) pressure.
