Give an example where physisorption changes to chemisorption with rise – InterviewSolution

1.	Give an example where physisorption changes to chemisorption with rise in temperature. Explain the reason for the change.
Answer» Solution :Physisorption of HYDROGEN on finely DIVIDED NICKEL involves weak van der Waal.s forces. With rise of temperature, hydrogen molecules dissociate into hydrogen atoms which are held on to the SURFACE by CHEMICAL bonds. i.e., chemisorption takes place.
