Chemisorption and physisorption both
Increases with increase in surface area
Increases with increase in temperature
decreases with increase in surface area
decreases with increase in temperature
Like physical adsorption, chemisorption also increases with the increase in the surface area of the adsorbent
Increases in the surface area mean an increase in the number of active sites in both types of adsorption.
So, option 1 is correct.
