Question

Which of the following reaction is not taking place in blast furnace during metallurgy of iron between the temperature range of 500-800 K?

• A. $\mathrm { FeO } + \mathrm { CO } \rightarrow \mathrm { Fe } + \mathrm { CO } _ { 2 }$
• B. $3 \mathrm { Fe } _ { 2 } \mathrm { O } _ { 3 } + \mathrm { CO } \rightarrow 2 \mathrm { Fe } _ { 3 } \mathrm { O } _ { 4 } + 4 \mathrm { CO } _ { 2 }$
• 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: (A)

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

Answer 2

This reaction takes place at 900-1500 K.
