Question
Below point ‘A’ \[\ce{FeO}\] can ______.
Options
be reduced by carbon monoxide only.
be reduced by both carbon monoxide and carbon.
be reduced by carbon only.
not be reduced by both carbon and carbon monoxide.
Solution
Below point ‘A’ \[\ce{FeO}\] can be reduced by carbon monoxide only.
Explanation:
Below the point A, Gibbs free energy change for the formation of \[\ce{CO2}\] from \[\ce{CO}\] has lower value than Gibb's free energy change for the formation of \[\ce{FeO}\]. \[\ce{ΔG_{(Fe, FeO)}}\].
