Assertion A: Reduction of metal oxide is easier if metal formed is in liquid state than solid state.
Reason R: becomes more negative as entropy is higher in liquid state than solid state.

Strategy:
 Analyze the thermodynamics of smelting/reduction processes using the Gibbs Energy relationship .

Step 1: Evaluate the Entropy change
Entropy follows the order: .
If the metal formed by reduction is in the liquid state () rather than the solid state, the entropy of the products is higher. This makes  more positive (or less negative).

Step 2: Link to Spontaneity
A more positive  makes the term  more negative. This lowers the overall , making the reduction spontaneous at lower temperat
