Question: What is the significance of the Langmuir isotherm in surface chemistry? (2023)

Options:

Correct Answer: It assumes a fixed number of adsorption sites.

Exam Year: 2023

Solution:

The Langmuir isotherm assumes a fixed number of adsorption sites and describes monolayer adsorption on a surface.

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.
