SUMMARY

The primary products of the silicon carbide (SiC) production reaction are carbon monoxide (CO) and carbon dioxide (CO2), with CO being the major product due to the excess presence of carbon. The ideal stoichiometric reaction is represented as SiO2 + 2C → SiC + CO2. The specific product gas can vary based on the reactants used, necessitating empirical calculations for accurate reactant weights. For further understanding, reference materials such as the Ellingham Diagram and textbooks by Levine or J.D. Lee are recommended.

I have a simple question.

What will be the products of the SiC producing reaction:
SiO2 + C = SiC + ?

(I twill be CO, CO2, O2 ?)

Thanks.

As you have written it the answer seems to be O2. It doesn't happen like that in practice. Usually carbon is present in excess and CO is the major product but CO2 can be produced as well. The ideal reaction would be written as:

SiO2 + 2C ------> SiC + CO2
 
Thanks chemisttree, but I must know exactly the product gas because I have to calculate empiric weight of the reactants.
 
THE evolution of CO or CO2 depends upon the substance used ...here COWILL BE EVOLVED ... fOR FURTHUR DETAIL U MAY REFER TO "ELLINGHAM DIAGRAM" 4m any higher level book...Levine or J.D.Lee...
