Which of the following diagram explain extraction of metal from metal oxide: (RPMT 2010)

In metallurgy, Ellingham diagram is used to predict the ease of reduction of the metal oxides and sulphides to metals. The diagram is used for the prediction of the equilibrium temperature between a metal and its oxide or sulphides. The diagram plots a graph between the free energy and the temperature. Therefore, the correct answer is option (a) Free energy V/s temp. 18. Mond’s process is used for: (AIPMT 2010) (a) Ni (b) Al (c) Fe (d) Cu Mond’s process is also known as carbonyl process. It is used for extraction and purification of nickel. In this process, nickel oxides are converted int
