Methylene blue, from its aqueous solution, is adsorbed on activated charcoal at 25^(@)C . Identify correct one (a)The adsorption requires activation at 25^(@)C (b)The adsorption is accompanied by a decrease in enthalpy (c)The adsorption increases with increases of temperature (d)The adsorption is irreversible

Adsorption is accompanied with

Why adsorption accompanied by decrease in entropy?

Assertion: Adsorption is exothermic and spontaneous in spite of the fact that adsorption is accompanied with deccrease in entropy. Reason: The factor TDeltaS is lesser than DeltaH

Why is adsorption accompanied by the decrease of both enthalpy as well as entropy of the system? Which factors help in increasing the extent of physical adsorption of the gas on charcoal powder?
