Question

The temperature of blast furnace to produce iron from its ore ${\rm{F}}{{\rm{e}}_2}{{\rm{O}}_3}$ varies from 500$^\circ C$ at the top of the furnace to about 1900$^\circ C$ at the bottom of the furnace. The reaction between the ore ${\rm{F}}{{\rm{e}}_2}{{\rm{O}}_3}$ and CO at the lowest temperature ($ \sim $500$^\circ C$) is:

Accepted Answer

${m{F}}{{m{e}}_2}{{m{O}}_3} + 3{m{CO}} 	o 2{m{Fe}} + 3{m{C}}{{m{O}}_2}$

Answer

$3{m{F}}{{m{e}}_2}{{m{O}}_3} + {m{CO}} 	o 2{m{F}}{{m{e}}_3}{{m{O}}_4} + {m{C}}{{m{O}}_2}$

Answer

${m{F}}{{m{e}}_2}{{m{O}}_3} + {m{CO}} 	o 2{m{Fe}}{{m{O}}_\;} + {m{C}}{{m{O}}_2}$

Answer

${m{F}}{{m{e}}_2}{{m{O}}_3} + {m{CO}} 	o 2{m{Fe}} + {m{C}}{{m{O}}_2} + \frac{1}{2}{{m{O}}_2}$
