प्रश्न
Give an example where physisorption changes to chemisorption with rise in temperature. Explain the reason for change.
उत्तर
The process of physisorption for example that of H2 on finely divided nickel, involves weak van der Waals’ forces. With increase in temperature, hydrogen molecules dissociate into hydrogen atoms which are held on the surface by chemisorption.
