General Principles & Processes of Isolating Elemen

Given below are two statements:

Statement I: According to the Ellingham diagram, any metal oxide with higher $\Delta G°$ is more stable that the one with lower $\Delta G°$ .

Statement II: The metal involved in the formation of oxide placed lower in the Ellingham diagram can reduce the oxide of a metal placed higher in the diagram.

In the light of the above statements, choose the most appropriate answer form the options given below:

Given are two statements one is labeled as Assertion A and other is labeled as Reason R.

 Assertion A : Magnesium can reduce Al₂O₃ at a temperature below 1350°C, while above 1350°C aluminium can reduce MgO

Reason R : The melting and boiling points of magnesium are lower thatn those of aluminium.
