Question

What is meant by adsorption isotherm what is the effect of pressure on physical adsorption?

Answer 1

Here is your answer:

An adsorption isotherm is a relation between the extent of adsorption (amount of a substance adsorbed per unit mass of an adsorbent) and the equilibrium pressure or concentration at a constant temperature.

Answer 2

Answer:

Adsorption Isotherm

Adsorption is usually described by isotherms. It is due to the fact that temperature plays an important role or that it has a great effect on the whole process. Moreover, there are several isotherm models that are used to describe the adsorption technique.
