Kinetic Salt Effect - Size of Ions

  1. Jun 20, 2016 #1
    Hello,

    Throwing out a question to see if anyone has some insight.

    The kinetic salt effect describes the variation of the rate constant of a reaction with respect to the ionic strength of the solution. The mathematical relationship considers the ionic strength (molality/ion charges) of the solution, but as described there would be no effect of ionic radius. Does anyone know if ionic radius can play a role in this? For example, would the magnitude of the kinetic salt effect be identical for a solution of 0.1 M NaCl as it would for 0.1M HCl?


    Thanks
    RP

    Probably not since the charge to mass ratio is higher for hydrogen than it is for sodium. That will affect the ionic strength of the solution.
