Vedclass · Answer

(B) An adsorption isobar is a plot of the extent of adsorption $(x/m)$ versus temperature $(T)$ at a constant pressure. For chemisorption,the process involves the formation of chemical bonds,which requires an initial activation energy. Therefore,as the temperature increases,the rate of adsorption initially increases due to the overcoming of the activation energy barrier. However,at higher temperatures,the desorption process becomes dominant due to the breaking of chemical bonds,causing the extent of adsorption to decrease. Thus,the plot of $x/m$ versus $T$ for chemisorption shows an initial increase followed by a decrease,which corresponds to the graph in option $B$.
