Langmuir Isotherms for a Binary Mixture
Langmuir isotherms are generated for each component in a binary gas-phase mixture of A and B. Vary the heats of adsorption of each component, the temperature, and the ratio of partial pressures with sliders. The molecules compete for adsorption sites but do not interact with each other, and this is taken into account in the form of the Langmuir isotherm. Vary the relative number of sites per molecule with a slider to account for larger molecules occupying more surface area than smaller molecules. The Langmuir isotherm for molecules A and B has the form:
