Q. The following reaction occurs in the Blast Furnace where iron ore is reduced to iron metal:
$\text{F}\left(\text{e}\right)_{2}\left(\text{O}\right)_{3}\left(\text{s}\right)+3\text{C}\text{O}\left(\text{g}\right) \, \, \rightleftharpoons2\text{F}\text{e} \, \left(\text{l}\right)+3\text{C}\left(\text{O}\right)_{2}\left(\text{g}\right)$
Using the Le Chatelier's principle, predict which one of the following will not disturb the equilibrium?

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 kp, kc,& kx expresssion.
So, it will not disturb the equilibrium
