Passage / Comprehension
The first stage in the conversion of iron ore to steel is the carbon reduction in blast furnace, which accounts for the largest tonnage of any metal produced by man. In it the iron ore is reduced by CO/coke, while limestone removes any sand or clay as a slag. The molten iron is run off to be cast into moulds of the required shape or into ingots ("pigs") for further processing.
Select INCORRECT option :
Options:
Answer:
B
Solution:
The reduction sequence in option B is incorrect. FeO reduces to Fe, not through intermediate oxides like Fe₃O₄ and Fe₂O₃, when reduced by CO. The correct sequence for iron oxides reduction by CO is Fe₂O₃ Fe₃O₄ FeO Fe.
Final Answer: The final answer is B
