The following reaction occurs in the Blast Furnace where iron ore is reduced to iron metal:

\text{F}{\text{e}}_{2}{\text{O}}_{3}\left(\text{s}\right) + 3\text{C}\text{O}\left(\text{g}\right) ⇌ 2\text{F}\text{e}\left(\text{l}\right) + 3\text{C}{\text{O}}_{2}\left(\text{g}\right)

Using the Le Chatelier's principle, predict which one of the following will not disturb the equilibrium?

Options

AAddition of $\text{C}{\text{O}}_{2}$
BRemoval of $\text{C}{\text{O}}_{2}$
CAddition of $\text{F}{\text{e}}_{2}{\text{O}}_{3}$
DRemoval of CO

Correct answer

C. Addition of $\text{F}{\text{e}}_{2}{\text{O}}_{3}$

Step-by-step solution

It is heterogeneous equilibrium Fe is liquid Fe₂O₃ is solid whose active mass is taken to be unity so, it will not be considered in k_p, k_c,& k_x expresssion.
So, it will not disturb the equilibrium
