adsortion ,absorption,sorption is exothermic or endothermic.........n explain y is it ?
though adsorption is exothermic in nature but both sorption and absorption are endothermic in nature ok,,,,,
adsorption is exothermic because during this process the residual forces on the surface of the adsorbent decreases which decreases the surface energy and this appears in the form of heat called heat of adsorption and therefore it is exothermic in nature
but in case of both absorption and sorption,,heat is required in order to make the particles get settled and hencce both are endothermic in nature
