The adsorption of an inert gases on activated charcoal increase with

  • A
    decrease of pressure
  • B
    increase of temperature
  • C
    decrease of atomic mass
  • Correct answer
    D
    decrease of temperature

Solution

Adsorption of an inert gases on activated charcoal increases with decrease of temperature as it is an exothermic process. The adsorption of gas on solid surface is similar to condensation process, which is exothermic in nature.

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