  4. Formation of strong bonds

Questions & Step-by-Step Solutions

Which of the following is a characteristic of physisorption?
  • Step 1: Understand what physisorption means. It is a type of adsorption where molecules stick to a surface.
  • Step 2: Learn about the forces involved in physisorption. It uses weak van der Waals forces.
  • Step 3: Recognize that physisorption is a reversible process. This means that the molecules can easily detach from the surface.
  • Step 4: Note that physisorption has a low heat of adsorption. This means it doesn't require much energy to occur.
