In Ellingham diagram, two metals A and B have Gibb’s Energy slopes going downward and upward respectively while crossing each other at T= 300K. Metal A starts from a higher point and metal B starts from a lower point. Which of the following statements are true regarding metals A and B?

Option: 1

A can reduce B before 300K


Option: 2

B can reduce A before 300 K.


Option: 3

A can reduce B at 300 K.


Option: 4

B can reduce A after 300K

The Gibbs’s energy of B is lower than that of A before 300K and the hence it can reduce A from its oxide to its metal form.
