Methylene blue, from its aqueous solution is adsorbed on activated cha – InterviewSolution

1.	Methylene blue, from its aqueous solution is adsorbed on activated charcoal at 25^(@)C.For this process, the correct statement is
Answer» The ADSORPTION REQUIRES activation at `25^(@)C` The adsorption is accompanied by a decrease in enthalpy. The adsorption increases with INCREASE of temperature The adsorption is irreversible. Solution :The adsorption of METHYLENE blue on activated charcoal is an example of PHYSIOSORPTION which is exothermic, multilayer and does not have energy barrier
