Which mechanism reduces required activation energy when using an iron catalyst to convert Haber-Bosch?

💡 Explanation

When using an iron catalyst in the Haber-Bosch process, surface adsorption weakens reactant bonds because the reactants bind to the catalyst surface; this lowers the energy needed to break the original bonds, promoting the reaction. Therefore, adsorption and weakened bonds reduce the required activation energy rather than raised concentration or increased reaction probability by other effect.
