SUMMARY

The discussion centers on the differences between using Iron(III) oxide (Fe2O3) and Iron(II) oxide (FeO) in thermite reactions to produce aluminum oxide (Al2O3). It is established that FeO has a lower enthalpy of formation compared to Fe2O3, suggesting that it may release more energy during the reaction. The Ellingham diagram is recommended as a valuable tool for understanding the thermodynamic stability of these oxides in thermite reactions.

PREREQUISITES
  • Understanding of thermite reactions
  • Knowledge of enthalpy of formation
  • Familiarity with the Ellingham diagram
  • Basic chemistry concepts related to oxidation states
NEXT STEPS
  • Research the thermodynamic principles behind thermite reactions
  • Study the Ellingham diagram in detail
  • Explore the properties and applications of Iron(II) oxide (FeO)
  • Investigate the energy output of different metal oxides in thermite reactions
USEFUL FOR

Chemistry students, materials scientists, and anyone interested in the thermodynamics of chemical reactions, particularly those involving metal oxides in thermite processes.

hey guys
i am wondering what the difference between using Fe2O3 or FeO would be in a thermite reaction to produce aluminium oxide.
wouldn't the FeO produce a more energy since its enthalpy of formation is lower?

thanks for your answers!

I am not sure about this but did you check out the ellingham diagram? This might give you the answer.
 
alright, thanks.
