Consider the following statements about Langmuir isotherm.
I. The free gas and adsorbed gas are in dynamic equilibrium.
II. All adsorption sites are equivalent.
III. The initially adsorbed layer can act as a substrate for further adsorption
IV. The ability of a molecule to get adsorbed at a given site is independent of the occupation of neighboring sites.
The correct statements are

View answer and explanation
Correct option: B
I, II and IV
Option A (C < N > O) is correct because nitrogen has a higher ionization energy than both carbon and oxygen due to its half-filled p orbitals.
