Question

Write one similarity between physisorption and chemisorption.

Answer 1

Both are Surface phenomenon and both increases with increase in surface area!

Answer 2

Hey !!

Both physisorption and chemisorptions increases with the increase in surface area per unit mass of the adsorbing substances.

  Both physisorption and chemisorption depend upon the nature of the substance adsorbed. Physisorption is possible easier for gases high critical temperature (Tc) while chemisorption takes place only if there is possibility of formation of covalent bond between the two substances.

GOOD LUCK !!
