Which phenomenon causes decreased ammonia production in Haber-Bosch process reactor at elevated temperatures?

💡 Explanation

When temperature increases in Haber-Bosch process, the equilibrium shifts towards reactants because the forward reaction (ammonia synthesis) is exothermic, leading to less ammonia production. Therefore equilibrium shift favoring reactants becomes dominant, rather than catalyst sintering, viscosity increase, or nitrogen adsorption issues which depend on catalyst properties.
