## Abstract The activation energy parameters for the reaction of PdX (X=Cl^−^, Br^−^) in aqueous halide acid solution with thiourea (tu) and selenourea (seu) have been determined. High rates of reaction parallel low enthalpies and appreciable negative entropy of activation. The rate law in each cas
