Adsorption

The given graphs/data I, II, III and IV represent general trends observed for different physisorption and chemisorption processes under mild conditions of temperature and pressure. Which of the following choice(s) about I, II, III and IV is (are) correct?

Among physisorption and chemisorption, which type of a adsorption has a higher enthalpy of adsorption?

20% of surface sites are occupied by $N_2$molecules. The density of surface sites is $6.023\times {10}^{14}{\mathrm{cm}}^{-2}$ and total surface area is $1000c{m}^2$. The catalyst is heated to 300 K while $N$ is completely desorbed into a pressure of 0.001 atm and volume of $2.46c{m}^3$. The number of active sites occupied by each $N_2$ molecule will be

Adsorption of gases on solid surface is generally exothermic because:
