Assertion: During the formation of lime in a lime klin .`CO_2` (g) formed in the reactions should continuously be removed
Reason: The pressence of `CO_2(g)` deteriorates the quality of lime produced.

Options

A. If both Assertion and Reason are CORRECT and a Reason is the CORRECT explanations of the Assertion
B. If both Assertion and Reason are CORRECT but Reaon is not CORRECT explanation of the Assertion.
C. If Assertion is CORRECT but Reasson is INCORRECT.
D. If Assertion is INCORRECT but Reason is CORRECT.

Answer

To solve the question regarding the assertion and reason related to the formation of lime in a lime kiln, we will analyze both statements step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that during the formation of lime in a lime kiln, `CO2` (g) formed in the reactions should continuously be removed.
- This is based on the chemical reaction:
\[ \text{CaCO}_3 (s) \rightarrow \text{CaO} (s) + \text{CO}_2 (g) \]
- In this reaction, calcium carbonate decomposes to form calcium oxide (lime) and carbon dioxide gas.

2. **Analyzing the Reason**:
- The reason given is that the presence of `CO2(g)` deteriorates the quality of lime produced.
- While `CO2` is a product of the reaction, its presence can affect the equilibrium of the reaction.

3. **Applying Le Chatelier's Principle**:
- According to Le Chatelier's Principle, if a system at equilibrium is disturbed, the system will adjust to counteract the disturbance and restore a new equilibrium.
- In this case, if `CO2` is continuously removed from the system, the equilibrium will shift to the right (forward direction) to produce more `CaO` and `CO2`, thereby increasing the yield of lime.

4. **Conclusion on Assertion and Reason**:
- The assertion is correct because removing `CO2` indeed helps in the continuous production of lime.
- However, the reason provided is not a valid explanation for the assertion. The quality of lime is not directly affected by the presence of `CO2`; rather, it is the equilibrium shift that is important for maximizing lime production.

5. **Final Answer**:
- Therefore, the correct conclusion is that the assertion is true, but the reason is false. The correct answer is: Assertion is correct, but Reason is incorrect.
