Q1 / 113 · NTA Abhyas (NEET) 2020 · Chemistry · Surface Chemistry

Which is correct in case of van der Waal's adsorption?

  • A
    High temperature, low pressure
  • Correct answer
    B
    Low temperature, high pressure
  • C
    Low temperature, low pressure
  • D
    High temperature, high pressure

Solution

Physical or van der Waal's adsorption is more pronounced at low temperature and high pressure as it is an exothermic process so low temperature and high pressure favours it.

Hence, the correct answer is option: 'B'.
