The complexes PdCl 4 2− , PdCl 3 (H 2 O) − , and PdCl 3 (Ac) 2− , in rapid equilibrium with each other under the adopted experimental conditions, react with ethylenediamine according to the experimental rate law\documentclass{article}\pagestyle{empty}\begin{document}$$ k_{{\rm obs}} = \left\{ {\frac{k}{{\left[{{\rm H}^{\rm + } } \right]}} + \frac{{k'}}{{\left[{{\rm H}^{\rm + } } \right]\left[{{\rm Cl}^{\rm - } } \right]}} + \frac{{k''\left[{{\rm Ac}^{\rm - } } \right]}}{{\left[{{\rm H}^{\rm + } } \right]\left[{{\rm Cl}^{\rm - } } \right]}}} \right\}\left[{{\rm en}} \right]_{{\rm total}}$$\end{document} A reaction scheme is proposed involving the reaction of enH + with each of the above species, and the specific rate constants are computed. The activation parameters are given.
