Which respect to an ore, Ellingham diagram helps to predict the feasibility of its

A
Electrolysis
B
Zone refining
C
Vapour phase refining
Correct answer
D
Thermal reduction

Solution

Ellingham diagram is a graph showing temperature dependence of the stability of compounds. This analysis is used to evaluate the case of Reduction of metal oxides and sulphides. This diagram also used to predict the equilibrium temperature between a metal and its oxide.

Hence, the correct answer is option: 'D'.
