The decomposition of ammonia on Pd.13 surface is occurring, in which, the ammonia is dissociated over the surface as: 2 NH, - N2+3 H2. The N2 gas species is also adsorbed on the surface, whereas the H, is not adsorbed on Pd surface. The rate law and how it reduces if the amount of N, adsorbed is greatly larger than that * :of ammonia on surface, respectively are Rate =k K,[NH]/(1+K,[NH]+Kg[N¿]): Rate =k K,[NH,]/K3[N‚] Rate =k K,[NH,]/(1+K,[NH,]+K„[H,]): Rate =k K,[NH3]/K[N,] Rate =k K,[NH3]/(1+K,[NH,J+K_[H,]): Rate =k K,[NHJ/(1+K,[HJ) Rate =k K,[NH]/(1+K,[NH,]+K3[N‚]): Rate =k K,[NH,J/(1+K,[N,])
