Vedclass · Accepted Answer

Physical adsorption takes place with decrease of free energy whereas chemical adsorption occurs with increase of free energy

Vedclass · Answer

(B) Both physical and chemical adsorption are spontaneous processes,meaning they occur with a decrease in Gibbs free energy $(\Delta G Physical adsorption is exothermic and decreases with an increase in temperature.Chemical adsorption also involves the formation of chemical bonds,which is exothermic,but it often requires an activation energy to initiate the process.Therefore,the magnitude of chemical adsorption may initially increase with temperature as more molecules overcome the activation energy barrier,while physical adsorption consistently decreases.Statement $(B)$ is incorrect because both types of adsorption occur with a decrease in free energy.
