The following reaction occurs in the Blast Furnace where ion ore is reduced to iron metal: \( \boldsymbol{F e}_{2} \boldsymbol{O}_{3}(\boldsymbol{s})+\boldsymbol{3} \boldsymbol{C O}(\boldsymbol{g}) \rightleftharpoons \boldsymbol{2} \boldsymbol{F} \boldsymbol{e}(l)+ \) \( 3 C O(g) \) Using Le Chatelier's principle, predict which of the following will not disturb the equilibrium?
- A. Addition of \( F e_{2} O_{3} \)
- B. Removal of \( C O_{2} \)
- C. Removal of \( \mathrm{CO} \)
- D. Addition of \( C O_{2} \)
Step-by-step solution
Le Chatelier's principle states that a system at equilibrium will shift to counteract disturbances. Adding a pure solid (Fe2O3) does not change its concentration (activity is constant), so the equilibrium is not disturbed. In contrast, removal of CO2 (product) shifts equilibrium right, removal of CO (reactant) shifts left, and addition of CO2 (product) shifts left.
