Answer and explanation
Correct answer: C. Finely divided iron
- Step 1: The industrial Haber-Bosch process synthesizes ammonia via the exothermic equilibrium .
- Step 2: To achieve acceptable reaction rates at moderate temperatures, a solid heterogeneous catalyst is required to lower activation energy.
- Step 3: Finely divided iron promoted with potassium and aluminum oxides serves as the catalyst.
