Question

(a) Out of C and CO, which is better reducing agent F or FeO in the upper part of the blast furnace (lower temperature).
(b) Why reducing agents like carbon and hydrogen are not used to reduce metallic oxides at high temperature.

Answer 1

Explanation:

(a) CO is better reducing agent than C

(b) Carbon and hydrogen are good reducing agents but they are not used to reduce metallic oxides at high temperatures. This is because, at high temperatures, they can react with the metals itself, thereby forming carbides and hydrides respectively which are not desired.
