Question

3. Suggest whether the decomposition of NBC by Nb20s at 1 atm pressure possible at 1500°C (1773 K). Given: AG°1173 <Nb2O3 >=

suggest whether the decomposition of NbC by Nb2O5 at 1 atm pressure possible at 1500°C (1773 K). Given:

deltaG°1173 <Nb2O5 >= -1,125.5 kJ/mol
deltaG°1173 <NbC> = -128.87 kJ/mol
delta G°1173 (CO)= -267.77 kJ/mol
