Q. Identify the reaction that does not take place in a blast furnace

KCETKCET 2008General Principles and Processes of Isolation of Elements

Solution:

The reaction takes place in blast furnace are

$3 FeO _{3}+ CO \longrightarrow 2 Fe _{3} O _{4}+ CO _{2}$

$CaCO \longrightarrow CaO + CO _{2}$

$C + CO _{2} \longrightarrow 2 CO$

$CaO + SiO _{2} \longrightarrow CaSiO _{3}$

$2 C + O _{2} \longrightarrow 2 CO$

Hence, the reaction

$2 Fe _{2} O _{3}+3 C \longrightarrow 4 Fe +3 CO _{2}$ is not take place in blast furnace.
