Langmuir Isotherm Calculator
Calculate surface coverage ($\theta$) and amount adsorbed
Formula: $\theta = \frac{K \cdot C}{1 + K \cdot C}$ and $q = q_m \cdot \theta$
Where $K$ is the Langmuir equilibrium constant, $C$ is concentration (or Pressure $P$), and $q_m$ is the maximum monolayer adsorption capacity.

Calculation Results
⚠️ The Langmuir model assumes monolayer adsorption onto a surface with a finite number of identical sites and no lateral interaction between adsorbed molecules. It may not fit accurately at very high pressures/concentrations where multilayer adsorption (BET isotherm) occurs.
