In certain cases, physisorption tansfers into chemisorption as tempera – InterviewSolution

1.	In certain cases, physisorption tansfers into chemisorption as temperature is increased. Explain with an example.
Answer» Answer :`H_2` is adsorbed on nickel by vander WALL's forces (i.e., physisorption) at ORDINARY TERMPERATURE. But if temperature is increased, molecules of `H_2` DISSOCIATE to from H atoms which are HELD on the surface of nickel by chemisorption.
