摘要：

The kinetics of replacement of 4-cyanopyridine (4-CNpy) bv CN- in [Fe(CN)5(4-CNpy)]3- have been studied in different concentrations of electrolyte. Plots of ln(k/k(w)) versus (gamma - gamma(W)), where the subscript w refers to pure water and gamma is the surface tension of the appropriate salt solution, gave a common straight line for all the electrolytes studied. This result seems to confirm the D character of the process studied and permits an estimate of the activation volume to be made from kinetic data.
