Question

Which of the following reaction takes place at higher temperature range (900 K -1500 K) in blast furnace?

• A. $3 \mathrm { Fe } _ { 2 } \mathrm { O } _ { 3 } + \mathrm { CO } \rightarrow 2 \mathrm { Fe } _ { 3 } \mathrm { O } _ { 4 } + \mathrm { CO } _ { 2 }$
• B. $\mathrm { FeO } + \mathrm { CO } \rightarrow \mathrm { Fe } + \mathrm { CO } _ { 2 }$
• C. $\mathrm { Fe } _ { 3 } \mathrm { O } _ { 4 } + 4 \mathrm { CO } \rightarrow 3 \mathrm { Fe } + 4 \mathrm { CO } _ { 2 }$
• D. $\mathrm { Fe } _ { 2 } \mathrm { O } _ { 3 } + \mathrm { CO } \rightarrow 2 \mathrm { FeO } + \mathrm { CO } _ { 2 }$

Answer 1

Answer: (B)

$\mathrm { FeO } + \mathrm { CO } \rightarrow \mathrm { Fe } + \mathrm { CO } _ { 2 }$

Answer 2

At 900-1500 K the reaction taking place in blast furnace are:

$\mathrm { C } + \mathrm { CO } _ { 2 } \longrightarrow 2 \mathrm { CO } , \mathrm { FeO } + \mathrm { CO } \rightarrow \mathrm { Fe } + \mathrm { CO } _ { 2 }$
