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

• A

  $\mathrm{CaCO}_{3} \longrightarrow \mathrm{CaO}+\mathrm{CO}_{2}$
• B

  $\mathrm{CaO}+\mathrm{SiO}_{2} \longrightarrow \mathrm{CaSiO}_{3}$
• Correct answer
  C

  $2 \mathrm{Fe}_{2} \mathrm{O}_{3}+3 \mathrm{C} \longrightarrow 4 \mathrm{Fe}+3 \mathrm{CO}_{2}$
• D

  $\mathrm{CO}_{2}+\mathrm{C} \longrightarrow 2 \mathrm{CO}$

Hence, the correct answer is option: 'C'.
