Question

Ellingham diagram is given below for the formation of some oxides. Then select the correct combination

  1. Below T subscript 2 end subscript comma A l subscript 2 end subscript O subscript 3 end subscript plus 3 M g text end text ® 3 M g O plus 2 A l comma D G equals negative v e    
  2. Below T subscript 3 end subscript comma M g O plus C O ® C O subscript 2 end subscript plus M g comma D G equals negative v e    
  3. Above T subscript 4 end subscript comma A l subscript 2 end subscript O subscript 3 end subscript plus 3 C O text end text ® text end text 2 A l plus 3 C O subscript 2 end subscript comma D G equals negative v e    
  4. Below T1 , MgO is in liquid state    

The correct answer is: Below T subscript 2 end subscript comma A l subscript 2 end subscript O subscript 3 end subscript plus 3 M g text end text ® 3 M g O plus 2 A l comma D G equals negative v e
