    Identify the reaction that does not take place in a blast furnace.

    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 \[3F{{e}_{2}}{{O}_{3}}+CO\xrightarrow{{}}2F{{e}_{3}}{{O}_{4}}+C{{O}_{2}}\] \[COC{{O}_{3}}\xrightarrow{{}}CaO+C{{O}_{2}}\] \[C+C{{O}_{2}}\xrightarrow{{}}2CO\] \[CaO+Si{{O}_{2}}\xrightarrow{{}}CaSi{{O}_{3}}\] \[2C+{{O}_{2}}\xrightarrow{{}}2CO\] Hence, the reaction                 \[2F{{e}_{2}}{{O}_{3}}+3C\xrightarrow{{}}4Fe+3C{{O}_{2}}\]is not take place in blast furnace.
