Chemistry NCERT Exemplar Solutions Class 12th Chapter Six Class 12th Chemistry

Given below are two statements : One is labeled as Assertion A and the other is labeled as Reason R

Assertion A: The reduction of a metal oxide is easier if the metal formed is in liquid state than solid state.

Reason R: The value of $Δ G^{Θ}$ becomes more on negative side as entropy is higher in liquid state than solid state.

**In the light of the above statements, choose the most appropriate answer from the options given below**

Option 1 - <p><strong>Both A and R are correct and R is the correct explanation of A</strong></p>

Option 2 - <p><strong>Both A are R correct but R is NOT the correct explanation of A</strong></p>

Option 3 - <p><strong>A is correct but R is not correct</strong></p>

Option 4 - <p><strong>A is not correct but R is correct</strong></p>

Correct Option - 3

Detailed Solution:

$Δ G = Δ H - T Δ S$

$∴ Δ$ S increases then (Ve) value of $Δ G$ increases and it is easy to reduce. Entropy of liquid is greater than solid. On melting, entropy increases and $Δ G$ becomes more negative.
