QNEET-2023-Ch-219: NEET 2023 Chemistry - Class 12 NEET-2023-Ch-219 Solution: The reaction that does NOT take place in blast furnace between…

The reaction that does NOT take place in blast furnace between 900 K to 1500 K temperature range during extraction of iron is:

FeO + CO \rightarrow Fe + CO_2

C + CO_2 \rightarrow 2CO

CaO + SiO_2 \rightarrow CaSiO_3

Fe_2O_3 + CO \rightarrow 2FeO + CO_2

A $\mathrm{FeO}+\mathrm{CO} \rightarrow \mathrm{Fe}+\mathrm{CO}_{2}$ FeO + CO _ Fe + CO 2 _
B $\mathrm{C}+\mathrm{CO}_{2} \rightarrow 2 \mathrm{CO}$ C + CO 2 _ _ 2 CO
C $\mathrm{CaO}+\mathrm{SiO}_{2} \rightarrow \mathrm{CaSiO}_{3}$ CaO + SiO 2 _ _ CaSiO 3 _
D $\mathrm{Fe}_{2} \mathrm{O}_{3}+\mathrm{CO} \rightarrow 2 \mathrm{FeO}+\mathrm{CO}_{2}$ Fe 2 _ O 3 _ + CO _ 2 FeO + CO 2 _

Step-by-Step Verified Solution

Reaction Fe 2 O 3 + CO _ 2 FeO + CO 2 This reaction takes place at temperature (500 K - 800 K) not at (900 K to 1500 K)
