Which phenomenon leads to decreased hydrogen production efficiency in a Haber-Bosch reactor operating at higher temperatures?

💡 Explanation

When temperature increases in the Haber-Bosch process, the equilibrium shifts toward the reactants (nitrogen and hydrogen) due to the endothermic nature of the reverse reaction according to Le Chatelier's principle, hindering ammonia formation. Therefore reactant preference emerges, instead of surface area reduction, faster decomposition, or nitrogen adsorption that exhibit differing drivers.
