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

Options

  1. ACaCO ₃ CaO + CO ₂
  2. BCaO + SiO ₂ CaSiO ₃
  3. C2 Fe ₂ O ₃+3 C 4 Fe +3 CO ₂
  4. DCO ₂+ C 2 CO

Correct answer

C. 2 Fe ₂ O ₃+3 C 4 Fe +3 CO ₂

Step-by-step solution

The reaction, 2 Fe ₂ O ₃+3 C 4 Fe +3 CO ₂ , do not occur in blast furnance. This reaction occurs at the end of the process.
