Question:

What does the Ellingham diagram consist of?

Options:

Plots of \(\Delta fG^0\) vs T

Plots of T vs \(\Delta fG^0\)

Plots of \(\Delta fG^0\) vs \(\Delta S\)

Plots of  \(\Delta S\) vs \(\Delta fG^0\)

Correct Answer:

Plots of \(\Delta fG^0\) vs T

Explanation:

Ellingham diagram normally consists of plots of \(\Delta fG^0\) vs T for formation of oxides of elements. Similar diagrams can also be constructed for sulphides and halides of elements. These diagrams help us in predicting the feasibility of thermal reduction of an ore.
