The following reaction occurs in the Blast Furnace where ions ore is reduced to iron metal :
`Fe_(2)O_(3)(s)+3CO(g)hArr 2Fe(l)+3CO_(2)(g)`
Using the Le Chatelier's principle, predict which one of the following will not disturb the equilibrium?

Options

A. Addition of `CO_(2)`
B. Removal of `CO_(2)`
C. Addition of `Fe_(2)O_(3)`
D. Removal of `CO`

Answer

To solve the problem using Le Chatelier's principle, we need to analyze the given equilibrium reaction:

\[ \text{Fe}_2\text{O}_3(s) + 3\text{CO}(g) \rightleftharpoons 2\text{Fe}(l) + 3\text{CO}_2(g) \]

### Step-by-Step Solution:

1. **Identify the Components of the Reaction:**
- Reactants: Fe₂O₃ (solid) and CO (gas)
- Products: Fe (liquid) and CO₂ (gas)

2. **Understand Le Chatelier's Principle:**
- Le Chatelier's principle states that if a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change and restore a new equilibrium.

3. **Evaluate Each Option:**
- **Option 1: Addition of CO₂**
- Adding CO₂ increases the concentration of a product. According to Le Chatelier's principle, the equilibrium will shift to the left (backward direction) to reduce the concentration of CO₂, thus disturbing the equilibrium.

- **Option 2: Removal of CO₂**
- Removing CO₂ decreases the concentration of a product. The equilibrium will shift to the right (forward direction) to produce more CO₂, thus disturbing the equilibrium.

- **Option 3: Addition of Fe₂O₃**
- Fe₂O₃ is a solid, and the concentration of solids does not affect the equilibrium position. Therefore, adding Fe₂O₃ will not disturb the equilibrium.

- **Option 4: Removal of CO**
- Removing CO decreases the concentration of a reactant. The equilibrium will shift to the left (backward direction) to produce more CO, thus disturbing the equilibrium.

4. **Conclusion:**
- The only action that will not disturb the equilibrium is the addition of Fe₂O₃ (solid). Therefore, the correct answer is **Option 3**.
