The shape of isobar for physical adsorption and adsorption isobar for chemisorption, respectively, are

  • A
    Figure
  • B
    Figure
  • C
    Figure
  • Correct answer
    D
    Figure

Solution

In case of physisorption, with increase in temperature, the extent of adsorption decreases while in case of chemisorption, with increase in temperature, the extent of adsorption increases initially and then starts decreasing. Figure
These are correct adsorption isobars.

Hence, the correct answer is option: 'D'.
