Questions & Step-by-Step Solutions

What is the significance of the Langmuir isotherm in surface chemistry? (2023)
  • Step 1: Understand that the Langmuir isotherm is a model used in surface chemistry.
  • Step 2: Know that it describes how molecules stick to a surface.
  • Step 3: Recognize that it assumes there are a limited number of spots (or sites) on the surface where molecules can attach.
  • Step 4: Realize that it focuses on monolayer adsorption, meaning only one layer of molecules can stick to the surface.
  • Step 5: Understand that this model helps predict how much of a substance will adhere to a surface under different conditions.
