The Langmuir adsorption isotherm is deduced using the assumption:
Options
- Athe adsorption sites are equivalent in their ability to adsorb the particles
- Bthe heat of adsorption varies with coverage
- Cthe adsorbed molecules interact with each other
- Dthe adsorption takes place in multilayers
Correct answer
A. the adsorption sites are equivalent in their ability to adsorb the particles
Step-by-step solution
Langmuir adsorption isotherm is based on that every adsorption site is equivalent and the ability of a particle to binding is independent of sites are either occupied or unoccupied. Related Theory The key difference between Freundlich and Langmuir adsorption isotherms is that Freundlich adsorption isotherm is empirical, whereas Langmuir adsorption isotherm is theoretical. The adsorption isotherm is a primary method that we can use to predict the adsorption capacity of a particular substance.
