Question

Give reason- The reduction of a metal oxide is easier if the metal formed is in liquid state at the temperature of reduction

Answer 1

I hope it will help you

Answer 2

Solution :- The entropy is higher if the metal is in liquid state than when it is in solid state.

$\rightarrow$ The value of entropy change (∆S) of the reduction process is more on positive side when the metal formed is in liquid state and the metal oxide being reduced is in solid state.

$\rightarrow$ Thus, the value of ∆$_{r}$G$^{-}$ becomes more on negative side and the reduction becomes easier.
