Question

What is Langmuir isotherm equation?

Answer

Langmuir isotherm equation is a useful chiefly for gaseous systems, for the amount of material absorbed on a surface as a function of pressure while the temperature is held constant, assuming that a single layer of molecules is absorbed; it is ƒ= ap - (1+αp), where ƒ is the fraction of surface covered, p is the pressure and α is a constant.
