A catalyst will speed up both the forward and the reverse reactions by providing a lower‑energy pathway (lowering the activation energy). It therefore makes the system reach equilibrium faster but does not change the equilibrium composition or the equilibrium constant (K) for the reaction. The position of equilibrium (amounts of NH3, O2, NO, H2O at equilibrium) and ΔH remain unchanged.
