Adsorption process may follow different behaviors depending on the type of process and the nature of surface and adsorbate. Following are the six different classes of isotherms based on IUPAC classification:

You should be able to match these figures with the types: weak interactions, pore filling; layer-by-layer adsorption on uniform surface; pure microporous solids; non-porous or macroporous solids; macroporous, weak interactions; mesoporous solids. Match these and provide your reasoning behind each matching within 2 sentences
