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
- AIn the production of glass, sodium is employed as a reducing agent. Sodium's thermodynamic potential is irrelevant in this case because it primarily serves as a fluxing agent.
- BIn the extraction of iron, carbon is used as a reducing agent due to its favorable thermodynamic properties. Carbon can effectively reduce iron ore (Fe2O3) to produce iron metal.
- CIn the extraction of aluminum, magnesium is utilized as a reducing agent. However, this choice is based on economic factors rather than thermodynamics.
- DIn the synthesis of ammonia, nitrogen gas (N2) is reduced with hydrogen gas (H2) using a suitable catalyst. This choice is independent of thermodynamic considerations.
Correct answer
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 (Fe2O3) to produce iron metal.
