Surface coverage is usually not measured directly. Instead, experimental measurements usually measure the volume of gas that will adsorb to a surface at a particular pressure.
These are equilibrium measurements, so we usually DON'T measure how adsorbed volume changes with time. We wait until it saturates (i.e. at infinite time), and use that value.
I have not enough words to thank you sir.
YOU ARE A HERO
Thank you very very much
I really didn't do anything too special... but I appreciate your kind words.
You are a life saver Sir ❤...Thank You
Very happy to help
I hope I was taught by you when I learned physical chemistry.
That's very kind, thanks
Thank you sir. I really required this video.
You're quite welcome. Happy to help
How is this laterally inverted. It's beautiful
You're not the first one to ask... See this video for a demonstration: th-cam.com/video/YmvJVkyJbLc/w-d-xo.html
love from Bangladesh....tnx sir
How do we measure the volume adsorbed with time?

Thank you for the prompt reply! Your content is a marvel of which I am a big fan!
