Identify the reaction that does not take place in a blast furnace.
- A \(\mathrm{CaCO}_{3} \longrightarrow \mathrm{CaO}+\mathrm{CO}_{2}\)
- B \(\mathrm{CaO}+\mathrm{SiO}_{2} \longrightarrow \mathrm{CaSiO}_{3}\)
- C \(2 \mathrm{Fe}_{2} \mathrm{O}_{3}+3 \mathrm{C} \longrightarrow 4 \mathrm{Fe}+3 \mathrm{CO}_{2}\)
- D \(\mathrm{CO}_{2}+\mathrm{C} \longrightarrow 2 \mathrm{CO}\)
Answer & Solution
Correct Answer
(C) \(2 \mathrm{Fe}_{2} \mathrm{O}_{3}+3 \mathrm{C} \longrightarrow 4 \mathrm{Fe}+3 \mathrm{CO}_{2}\)
Step-by-step Solution
Detailed explanation
The reaction, \(2 \mathrm{Fe}_{2} \mathrm{O}_{3}+3 \mathrm{C} \longrightarrow 4 \mathrm{Fe}+3 \mathrm{CO}_{2}\), do not occur in blast furnance. This reaction occurs at the end of the process.
