A) chemical force
B) electrostatic force
C) van der Waal?s force
D) None of these
Correct Answer: C
Solution :
Physisorption is a process in which the electronic structure of the atom or molecule is barely perturbed upon adsorption. Gaseous molecules are attached to adsorbent by weak van der Wall?s force of attraction. Even though the interaction energy is very weak, \[(i.e.,\,\,10-100 MeV)\]You need to login to perform this action.
