The Langmuir adsorption isotherm is deduced using the assumption
A
the adsorption sites are equivalent in their ability to adsorb the particles
B
the heat of adsorption varies with coverage
C
the adsorbed molecules interact with each other
D
the adsorption takes place in multilayers.
Explanation
Langmuir adsorption isotherm is based
on the assumption that every adsorption site is
equivalent and that the ability of a particle to
bind there is independent of whether nearby sites
are occupied or not occupied.
