In metallurgy, the choice of a reducing agent in a particular case depends on thermodynamic factors. Which of the following examples illustrates this statement?

Options

  1. AIn the production of glass, sodium is employed as a reducing agent. Sodium's thermodynamic potential is irrele
  2. BIn the extraction of iron, carbon is used as a reducing agent due to its favorable thermodynamic properties. C
  3. CIn the extraction of aluminum, magnesium is utilized as a reducing agent. However, this choice is based on eco
  4. DIn the synthesis of ammonia, nitrogen gas (N 2 ) is reduced with hydrogen gas (H 2 ) using a suitable catalyst

Correct answer

B. In the extraction of iron, carbon is used as a reducing agent due to its favorable thermodynamic properties. C

Step-by-step solution

Correct Option is : (B) In the extraction of iron, carbon is used as a reducing agent due to its favorable thermodynamic properties. Carbon can effectively reduce iron ore (Fe 2 O 3 ) to produce iron metal.
