## Langmuir isotherm equation

[′laŋ‚myu̇r ′īs·ə‚thərm i‚kwā·zhən] (physical chemistry)

An equation, useful chiefly for gaseous systems, for the amount of material adsorbed on a surface as a function of pressure, while the temperature is held constant, assuming that a single layer of molecules is adsorbed; it is ƒ =

*ap*/(1 +*ap*), where ƒ is the fraction of surface covered,*p*is the pressure, and*a*is a constant.Want to thank TFD for its existence? Tell a friend about us, add a link to this page, or visit the webmaster's page for free fun content.
