Vedclass · Answer

(C) Graph $I$ shows that the amount adsorbed decreases with an increase in temperature at constant pressure. This is a characteristic feature of physisorption,as it is an exothermic process.Graph $II$ shows that the amount adsorbed increases with an increase in temperature. This is a characteristic feature of chemisorption,as it requires activation energy.Graph $III$ shows the effect of temperature on adsorption at constant pressure,where adsorption decreases as temperature increases (from $200 \ K$ to $250 \ K$),which is characteristic of physisorption.Therefore,$I$ represents physisorption,$II$ represents chemisorption,and $III$ represents physisorption.Thus,the correct statement is that $I$ is physisorption and $II$ is chemisorption.

The given graphs $I$,$II$,and $III$ represent general trends observed for different physisorption and chemisorption processes under mild conditions of temperature and pressure. Which of the following statements are correct?
