In the Langmuir adsorption isotherm, what does the term 'monolayer coverage' refer to?
Complete saturation of the surface
Partial coverage of the surface
Formation of multilayers
No adsorption
Monolayer coverage in the Langmuir isotherm indicates that all available adsorption sites on the surface are occupied by adsorbate molecules.

Q: In the Langmuir adsorption isotherm, what does the term 'monolayer coverage' refer to?
Solution: Monolayer coverage in the Langmuir isotherm indicates that all available adsorption sites on the surface are occupied by adsorbate molecules.
Steps: 5
Step 1: Understand what adsorption means. Adsorption is when molecules stick to a surface.
Step 2: Know that a surface has a limited number of spots where molecules can stick, called adsorption sites.
Step 3: Realize that 'monolayer' means a single layer. So, monolayer coverage means one complete layer of molecules on the surface.
Step 4: In monolayer coverage, every available adsorption site on the surface is filled with an adsorbate molecule.
Step 5: This means there are no empty spots left for more molecules to stick to the surface.
