Questions & Step-by-Step Solutions
The Langmuir isotherm assumes that adsorption occurs at specific sites on the surface. What does this imply? (2020)
Step 1: Understand that adsorption is the process where molecules stick to a surface.
Step 2: The Langmuir isotherm model suggests that there are specific spots on a surface where these molecules can attach.
Step 3: Each of these specific spots can hold only one molecule at a time, meaning that no two molecules can occupy the same spot.
Step 4: Because of this, the model predicts that the surface will eventually become fully covered with molecules, forming a single layer, known as a monolayer.
Step 5: This implies that once all the specific sites are filled, no more molecules can attach to the surface.
