Comment on the enthalpy and entropy change during the process of adsorption.
Asked by Topperlearning User | 29 May, 2014, 01:02: PM
Expert Answer
Important factor featuring adsorption is heat of adsorption. It is an exothermic process and ΔH adsorption is always negative as there is a decrease in residual forces on the surface. As the molecule adheres to the surface, the residual force decreases and as the movement is restricted so entropy ΔS also decreases.
