The rate coefficient including hydrodynamic repulsion

To solve eqn. (214) subject to ths usual Smoluchowski boundary conditions requires two integrations following the approach of Mozumder [315]. Deutch and Felderhof [70] showed that the rate coefficient was 

This is rather an abstruse expression. There are three limiting forms for Rea, which indicate the behaviour of the rate coefficient.

There is broad agreement between these results and those deduced by Emeis and Fehder [456a] from their molecular dynamics calculation. Finally, for reaction of neutral species with each other, Rice [484] found that the time-dependent rate coefficient was of the form
