the following adsorption isotherms: Langmuir, BET, Temkin, and
Freundlich. Indicate when and why each is likely to be
appropriate.
thats the complete question.
(a) Derive Freundlich and Langmuir isotherm equations.
(b) An aqueous solution containing a valuable solute is colored
by a small amount of an impurity. Before crystallization, the
impurity is to be removed by adsorption on a decoloring carbon
which adsorps only insignificant amount of the principal solute.

How can I analytically (and step by step) derive from this
equation that the IS curve slopes downwards? Please explain
thoroughly. TIA
