**Step-by-Step Solution:** 1. **Understanding Adsorption**: Adsorption is the process by which atoms, ions, or molecules from a gas, liquid, or dissolved solid adhere to a surface. In this case, we are discussing the adsorption of nitrogen (N₂) on the surface of iron (Fe). 2. **Nature of Nitrogen**: Nitrogen is a diatomic molecule (N₂) that is relatively inert at room temperature due to the strong triple bond between the nitrogen atoms. However, it can interact with metal surfaces under certain conditions. 3. **Temperature Influence**: The adsorption of nitrogen on iron is influenced by temperature. At low temperatures, nitrogen molecules are physisorbed onto the surface of iron. Physisorption involves weak van der Waals forces and does not involve significant energy changes. ...
