Langmuir Isotherm Calculator

Computing the fraction or percent of the adsorbent surface covered by an adsorbate

Input

Output

Surface Fraction (θ)
0
Surface Percent
0

Formula

  • θ = Fraction of the surface covered by adsorbate
  • Keq = Equilibrium constant of adsorbtion
  • P = Partial pressure of the gas

Defination / Uses

Using the Langmuir model, the Langmuir Isotherm calculator calculates the fraction or percent of the surface of the adsorbent covered by an adsorbate.

Adsorption

A process of adhesion that connects molecules, atoms, or ions to a surface (or a phase boundary).

Chemisorption

Chemisorption is a type of adsorption in which the adsorbate and the adsorbent form strong chemical interactions.

Isotherm

A function that describes the change in the amount of adhered substance, depending on the substance's partial pressure or concentration. Use the upper given formula for manual calculations. No sign-up, registration OR captcha is required to use this tool.
