Which of following forces is responsible for physisorption ?

Step-by-step solution

Physisorption, also known as physical adsorption, arises due to weak van der Waals forces between the adsorbate and the adsorbent. London force of dispersion is a type of van der Waals force and is the primary force responsible for physisorption. Coulombic and electrostatic forces are strong forces typically associated with ionic interactions or chemisorption, while hydrogen bonding is a specific dipole-dipole interaction not universally responsible for physisorption. Answer: London force of dispersion
