General Principles and processes of Isolation of Elements
medium
The reaction that does NOT take place in a blast furnace between $900\,K$ to $1500\,K$ temperature range during extraction of iron is :
A
$CaO + SiO _2 \rightarrow CaSiO _3$
B
$Fe _2 O _3+ CO \rightarrow 2 FeO + CO _2$
C
$FeO + CO \rightarrow Fe + CO _2$
D
$C + CO _2 \rightarrow 2 CO$
(NEET-2023)
Solution
At $900-1500\,K$ (higher temperature range in the blast furnace)
Reaction which take place are :-
$C + CO _2 \rightarrow 2 CO$
$FeO + CO \rightarrow Fe + CO _2$
$CaO + SiO _2 \rightarrow CaSiO _3 \text { (Slag formation) }$
$Fe _2 O _3+ CO \rightarrow 2 FeO + CO _2 \rightarrow \text { This take place at } 500-800\,K \text {. }$
