2nd ASSIGNMENT
(100p) 1) Gibbs free energy of the formation of one mole of pure TiO2
pure Ti (s) and pure oxygen gas is given as:
Ti (s) + O2 (g) = TiO2 (s)
(s)
from
ΔG°TiO2 = - 446230 + 88.9 T J/mole
Discuss, based on calculations, whether Ti can be oxidized inside a heat-treatment
furnace, which works at 10YZ oC and 1 atm air (oxygen and nitrogen mixture)
pressure.
(Use A, B, X, Y, and Z values from your student number as 20AB512XYZ),
(For example, if your student number is 2034512678, then the question will
be: “1078 oC” under 1 atm pressure)
