Discussion Overview

The discussion revolves around the chemical reaction between carbon monoxide and iron (III) oxide, specifically in the context of iron production in a blast furnace. Participants explore the correct stoichiometric equations for this reaction.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant proposes the reaction 3Fe2O3 + CO = 2Fe3O4 + CO2.
  • Another participant suggests that the reaction occurs in a blast furnace to produce iron, implying a need for a different equation.
  • Subsequent attempts to formulate the reaction include Fe3O + CO = 3Fe + CO2, which is challenged as incorrect.
  • A later reply provides a partial equation: Fe2O3 + 3CO = 2Fe + 3CO2, indicating a progression towards the correct formulation.
  • Finally, one participant confirms the equation Fe2O3 + 3CO = 2Fe + 3CO2 as correct, expressing satisfaction with the response.

Areas of Agreement / Disagreement

While there is a progression towards a correct equation, initial disagreements and corrections indicate that multiple views were present before arriving at a consensus on the final equation.

Contextual Notes

Some participants' equations contained errors or were incomplete, and the discussion reflects an iterative process of refining the chemical reaction representation.

Carbon monoxide reacts with the iron (lll) oxide.
Would it be like this...

3Fe2 O3 + CO= 2Fe3 O4 + CO2

Not quite. Would it help if I said this reaction is carried out is a blast furnace to produce iron?

No, but your getting warmer. I start by writing the reantant side for you;

Fe_{2}O_{3} _{s} + 3CO_{g} \rightarrow

and in words;

Iron(III) Oxide + Carbon Monoxide \rightarrow

so

Fe2O3 + 3CO = 2Fe + 3CO2

Is this right?
