What is Langmuir adsorption isotherm?
An equation used to describe the amount of gas adsorbed on a plane surface, as a function of the pressure of the gas in equilibrium with the surface. The Langmuir adsorption isotherm can be written: , where θ is the fraction of the surface ... Read More »

What is the difference between the Freundlich BET and Langmuir ad...
There are a few differences, but the main one is that Langmuir can only be used for surfaces which are cover by only one layer of gas and the BET surface area is calculated using the multilayer model. Read More »

1 Langmuir = 1 adsorbed monolayer. If I remember correctly (don't take my word for this), it is roughly the amount of gas deposited when a surface is exposed to 10^-6 torr for one second.

You mean isolate a? You do this: s = abc/(1 + ac) => s(1 + ac) = abc => s + sac = abc => s = abc - sac => s = a(bc - sc) => s/(bc - sc) = a => a = s/(bc - sc) = s/c(b-s)
