Questions & Step-by-Step Solutions

In the Langmuir adsorption isotherm, what assumption is made about the adsorption sites?
  • Step 1: Understand that the Langmuir adsorption isotherm is a model used to describe how molecules stick to a surface.
  • Step 2: Know that the model assumes there are specific spots on the surface where molecules can attach, called adsorption sites.
  • Step 3: Recognize that the key assumption of the Langmuir isotherm is that all these adsorption sites are the same.
  • Step 4: Realize that because the sites are identical, they all have the same energy for adsorption, meaning they behave uniformly.
