Which of the following is incorrect for physisorption?

Options

  1. AReversible
  2. BIncreases with increase in temperature.
  3. CLow heat of adsorption.
  4. DIncreases with increase in surface area.

Correct answer

B. Increases with increase in temperature.

Step-by-step solution

Since, the adsorption process is exothermic, the physical adsorption occurs readily at low temperature and decreases with increase in temperature (Le-Chatelier's principle).
