Consider the following ellingham diagram
Carbon based reduction of to give metal and acidic oxide of Carbon occurs above which temperature?
Options:
Answer:
B
Solution:
Carbon can reduce metal oxide M′O only when the carbon oxidation line lies below the M′O line in the Ellingham diagram.
This condition is achieved after the intersection point of the two lines.
From the graph, the intersection occurs near 2550 K.
Hence, carbon-based reduction of M′O becomes possible above 2550 K.
Answer: (B) 2550 K
