Question

In metallurgy, the choice of a reducing agent in a particular case depends on thermodynamic factors. Which of the following examples illustrates this statement?, In 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., 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., In the extraction of aluminum, magnesium is utilized as a reducing agent. However, this choice is based on economic factors rather than thermodynamics., In the synthesis of ammonia, nitrogen gas (N 2 ) is reduced with hydrogen gas (H 2 ) using a suitable catalyst. This choice is independent of thermodynamic considerations.
