Select the correct statement whenlower the position of a metal line in the Ellingham diagram

Answer»

The greater is the stability of it's oxide for example the line for AL (oxidation of Al) is FOUND to be below that for Fe (formation of `Fe_(2)O_(3))`
The greaterthe gap between any two lines the greater the effectiveness of reducing properties correcsponding to the lower line's METAL
The intersection of two lines implies an oxidition reduction equilibrium
At the point of intersection the free energy change for redox reaction is zero involving change for redox reaction is zero involving metal oxide and metal from that two lines.
