Reduction of metal oxide to metal become easier if the metal obtained in liquid state ? why ?

Solution

The temperature of the substance in liquid state is higher. The Ellingham diagram suggests that the value of $Δ G$ for the formation of metal oxides increases as the temperature increases. The reduction of metal oxide to metal is possible if the Gibbs energy is negative. Therefore, the reduction of metal oxide to metal is easier if the metal obtained in liquid state.
