Question
3. Fe and FeQ are in equilibrium with gas mixture of composition 71.8% CO-28.2%CO2 at
1273K. Which of the two solid phases disappears if the composition of the gas is held
constant and temperature of the system is increased?
Fe(s)+1/2O2(g)=FeO(s)
AG=-2
0=-263700+64.35T
ammmm
C(s)+O2 (g)= CO2(g)
AG=-394100-0.84T
C(s) + 1/2O2 (g) = CO AG=-111700-87.65T
