Redlich-Peterson Isotherm

The Redlich-Peterson isotherm is a hybrid of the Langmuir and Freundlich isotherms.  The numerator is from the Langmuir isotherm and has the benefit of approaching the Henry region at infinite dilution.  The denominator has the hybrid Langmuir-Freundlich form.

Redlich-PetersonThe Redlich-Peterson isotherm may be rearranged to a linear form.
