BET isotherm deals with multilayer adsorption on a substrate, shown as below equation: $!=$&$\text{'}...(6)$Where z p$/$p$*,$ p$*$ is the vapour pressure above a layer of adsorbate that is more than one molecule thick and which resembles a pure bulk liquid. Vmon is the volume corresponding to monolayer coverage, and c is a constant which is large when the entalphy of desorption from a monolayer is large compared with the entalphy of vaporization of liquid adsorbate. The data in Table Q$4($b$)$ relate to the adsorption of N$2$ on rutile $($TiO$2)$ at $75$ K$.$ Confirm that it fit a BET isotherm in the rage of pressure reported, and determine the value of Vmon and c$.$MATR $2313$ Thermodynamics of Materials$(15)$b$)!()*\text{'})\{)*()*$&$)\text{'}\}"$#$p$/$torr $1\mathrm{.}20$ V$/$mm$3601$Table Q$4($b$)$ : Adsorption of N$2$ on rutile surface$14\mathrm{.}045\mathrm{.}887\mathrm{.}5127\mathrm{.}7164\mathrm{.}4204\mathrm{.}7720822935104611461254$
