Assertion : Reduction of a metal oxide is easier if the metal formed is in liquid state at the temperature of reduction. Reason : Ihe entropy is higher if the metal is in liquid state.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion .
B. if both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Answer

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Understand the Assertion
The assertion states: "Reduction of a metal oxide is easier if the metal formed is in a liquid state at the temperature of reduction."

- **Explanation**: When a metal oxide is reduced, the metal is extracted from its oxide form. If the metal is in a liquid state during this process, it can flow and separate more easily from the oxide, making the reduction process more efficient.

### Step 2: Understand the Reason
The reason states: "The entropy is higher if the metal is in liquid state."

- **Explanation**: Entropy is a measure of disorder in a system. In general, liquids have higher entropy than solids because the particles in a liquid can move more freely, leading to a greater number of possible arrangements. Therefore, when the metal is in a liquid state, the entropy of the system is indeed higher.

### Step 3: Connect Assertion and Reason
Now, we need to determine if the reason correctly explains the assertion.

- The assertion is true because having the metal in a liquid state does make the reduction easier.
- The reason is also true because the entropy is indeed higher in the liquid state.

Furthermore, the reason explains why the assertion is true: higher entropy in the liquid state contributes to the ease of reduction of the metal oxide.

### Step 4: Conclusion
Since both the assertion and the reason are true, and the reason correctly explains the assertion, the correct answer is:

**Option A**: Both assertion and reason are true, and reason is the correct explanation of assertion.
