JEE MAIN - Chemistry (2024 - 5th April Morning Shift - No. 19)
The following reaction occurs in the Blast furnance where iron ore is reduced to iron metal
$$\mathrm{Fe}_2 \mathrm{O}_{3(s)}+3 \mathrm{CO}_{(g)} \rightleftharpoons \mathrm{Fe}_{(\mathrm{l})}+3 \mathrm{CO}_{2(g)}$$
Using the Le-chatelier's principle, predict which one of the following will not disturb the equilibrium.
Addition of $$\mathrm{CO}_2$$
Removal of $$\mathrm{CO}$$
Addition of $$\mathrm{Fe}_2 \mathrm{O}_3$$
Removal of $$\mathrm{CO}_2$$
Explanation
For the reaction :
$$\mathrm{Fe}_2 \mathrm{O}_{3(\mathrm{~s})}+3 \mathrm{CO}_{(\mathrm{g})} \rightleftharpoons \mathrm{Fe}_{(\mathrm{l})}+3 \mathrm{CO}_{2(\mathrm{~g})}$$
Addition or removal of $$\mathrm{Fe}_2 \mathrm{O}_{3(\mathrm{s})}$$ and/or $$\mathrm{Fe}_{\text {(l) }}$$ will not affect the equilibrium quotient and the equilibrium.
