Vedclass · Answer

(C) Chemisorption is an exothermic process that requires activation energy. Initially,as temperature increases,the rate of adsorption increases because more molecules gain the necessary activation energy to form chemical bonds with the surface. However,as the temperature continues to rise,the exothermic nature of the process causes the equilibrium to shift towards desorption,leading to a decrease in the amount of gas adsorbed $(x/m)$. Therefore,the graph of $x/m$ versus $T$ for chemisorption shows an initial increase followed by a decrease,resulting in a peak.
