A) Reaction \[F{{e}_{3}}{{O}_{4}}+4CO\xrightarrow{{}}3Fe+4C{{O}_{2}}\] belongs to lower temperature range (500 - 800K) of the blast furnace.
B) Reaction \[FeO+CO\xrightarrow{{}}Fe+C{{O}_{2}}\] belongs to higher temperature range (900 -1500K) of the blast furnace.
C) The iron obtained from blast furnace is cast iron with 3% carbon.
D) For reduction of iron oxide to occur \[\Delta G\] of the couple of following reactions should be negative \[FeO(s)\xrightarrow{{}}Fe(s)+\frac{1}{2}{{O}_{2}}(g)\] \[C(s)+\frac{1}{2}{{O}_{2}}(g)\xrightarrow{{}}CO(g)\]
Correct Answer: C
Solution :
[c] The iron obtained from blast furnace is pig iron with 4% carbon and impurities like S,P, Mn etc., in small amount.
