On the basis of Ellingham diagram which of the following is/are correct.

Entropy change for all metal oxides is roughly same.

Below the boiling point, 'TDS' factor is same irrespective of metal.

Above DG = 0 line, oxide decomposes into metal & oxygen.

If randomness increases the slope increases

Text Solution

Verified by Experts

The correct answer is:

CHECK THE SOLUTION.

(b, c, d)

= – Δ S , is slope in Ellingham diagram. Which is same below the boiling point.

Below the boiling point slope is same as factor T Δ S is same.

Above Δ G = 0 line free energy becomes positive so oxide decomposes.

Random increases i.e. Δ S increases, so slope also increases.
