Adsorption: Interactive Simulation

This simulation runs on your browser. Try to predict the behavior when a parameter changes before using a slider to change that parameter. A

Langmuir Isotherms for a Binary Mixture

Try to answer these questions before determining the answer with the simulation. We suggest that you write down the reasons for your answers.

  1. For mixture of A and B adsorbing on a surface, if the heat of adsorption for molecule B increased while keeping other parameters the same, what happens to the coverage of A molecules?
  2. For mixture of A and B adsorbing on a surface, suppose the heat of adsorption of molecule B is greater than the heat of adsorption of molecule A. What happens to the relative coverage of B to A as the temperature increases?
