Given below are two statements: One is labelled as Assertion \mathbf{A} and the other is labelled as Reason \mathbf{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  \Delta G ^{\Theta} 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

Both A and R are correct and R is the correct explanation of A
 


Option: 2

Both A and R are correct but R is NOT the correct explanation of A
 


Option: 3

A is correct but R is not correct
 


Option: 4

A is not correct but R  is correct

As we know -
\mathrm{\Delta G= \Delta H-T\Delta S}

as entropy of liquid is more than solid so on melting the entropy increases and \mathrm{\Delta G} becomes more negative leading to ease in reducung metal.

Hence it can be said that reduction of a metal oxide is easier if he metal formed is in liquid state than solid state which is explained by \mathrm{\Delta G} factor explained above

Hence option (A) is correct.
