What factor determines the strength of van der Waals’ forces near the critical temperatures?

Options

  1. ANature of the adsorbate
  2. BSize of the adsorbent particles
  3. CPressure of the adsorption process
  4. DTemperature of the adsorption process

Correct answer

D. Temperature of the adsorption process

Step-by-step solution

The paragraph suggests that the strength of van der Waals’ forces is influenced by the critical temperatures of gases, and these forces are stronger near the critical temperatures.
