Langmuir adsorption model

Okay kiddo, let me explain the Langmuir adsorption model to you in a way that's easy to understand.

Imagine you have a bunch of little magnets that you're trying to stick on to a fridge. The magnets are like gas molecules that are floating around in the air. The fridge is like a surface that the gas molecules can stick to.

Now, at first, there are a lot of open spots on the fridge where the magnets can stick. So the magnets start sticking to the fridge pretty quickly.

But as more and more magnets stick to the fridge, there are fewer and fewer open spots for the remaining magnets to stick. This means that it becomes harder and harder for the remaining magnets to stick to the fridge.

Eventually, all the spots on the fridge get filled up with magnets, and there's nowhere else for any more magnets to stick.

This is kind of like the Langmuir adsorption model. The model is used to explain how gas molecules stick to a solid surface (like the fridge). The model says that there is a limited number of spots on the surface where the gas molecules can stick.

At first, it's easy for the gas molecules to stick to the surface. But as more and more gas molecules stick, there are fewer and fewer spots left for the remaining gas molecules to stick. This means that the rate at which gas molecules stick to the surface slows down over time, until eventually, all the spots on the surface are filled up and no more gas molecules can stick.
