Arguments are given m favour of a mechamsm for surface reactions mvolwng &rect colhslons between chemlsorbed species and molecules or atoms that are trapped m the nelghbourhood of the surface but have not thermahzed Where such 'hot precursors' are revolved, the d~stmctlon between the classic Eley-R~deal and
Langmmr Hlnshelwood mechamsms is ill-defined Charactensuc features of precursor mechamsms are that they h) may lead to a non-thermal energy &stnbutlon of products, and (ll) will strongly influence reacuon rates of, e g catalytic reactions
