A) \[CaC{{O}_{3}}\xrightarrow{{}}CaO+C{{O}_{2}}\]
B) \[CaO+Si{{O}_{2}}\xrightarrow{{}}CaSi{{O}_{3}}\]
C) \[2F{{e}_{2}}{{O}_{3}}+3C\xrightarrow{{}}4Fe+3C{{O}_{2}}\]
D) \[C{{O}_{2}}+C\xrightarrow{{}}2CO\]
Correct Answer: C
Solution :
The reaction takes place in blast furnace are \[3F{{e}_{2}}{{O}_{3}}+CO\xrightarrow{{}}2F{{e}_{3}}{{O}_{4}}+C{{O}_{2}}\] \[CaC{{O}_{3}}\xrightarrow{{}}CaO+C{{O}_{2}}\] \[C+C{{O}_{2}}\xrightarrow{{}}2CO\] \[CaO+Si{{O}_{2}}\xrightarrow{{}}CaSi{{O}_{3}}\] \[2C+{{O}_{2}}\xrightarrow{{}}2CO\] Hence, the reaction\[2F{{e}_{2}}{{O}_{3}}+3C\xrightarrow{{}}4Fe+3C{{O}_{2}}\] is not take place in blast furnace.
