Enthalpy level diagram for the Haber process

An example figure from the Potential Energy Diagram generator.

Energy level diagram with N₂ + 3H₂ on a line at 0 kJ and 2NH₃ on a lower line at −92 kJ, with an arrow labeled ΔH = −92 kJ between them — An energy level diagram for the Haber process, N₂ + 3H₂ → 2NH₃: no curve, just the reactants and products as lines, with the ΔH arrow pointing down from the reactants at 0 kJ to the products at −92 kJ. The reaction gives out 92 kJ of heat, so it is exothermic.
