Which of the following is correct statement?

Options

A. Physisorption occurs at low temperature and chemisorption occurs at high temperature
B. Physisorption occurs at vary high temperature and chemisorption occurs at low temperature
C. Physisorption is irreversible and chemisorption is reversible
D. None of the above

Answer

A

Explanation

At high temparature, kinetic energy of adsorbate increases and make a strong chemical bond between adsorbate and adsorbent, hence chemisoption occurs.
