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

$\text{F}{\text{e}}_2{\text{O}}_3\left(\text{s}\right)+3\text{C}\text{O}\left(\text{g}\right)\rightleftharpoons 2\text{F}\text{e}\left(\text{l}\right)+3\text{C}{\text{O}}_2\left(\text{g}\right)$

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

• A

  Addition of $\text{C}{\text{O}}_2$
• B

  Removal of $\text{C}{\text{O}}_2$
• Correct answer
  C

  Addition of $\text{F}{\text{e}}_2{\text{O}}_3$
• D

  Removal of CO

Hence, the correct answer is option: 'C'.
