Hi,

What source do you have for the equation for the Kisliuk adsorption isotherm (d theta / dt)?

It fits perfectly to my data, but I can't quite figure out how you arrived at the term from the above equation, or Kisliuk's paper (J. Phys. Chem. Solids, 3, p95 (1957)).

Any help would be much appreciated.
