The adsorption of an inert gases on activated charcoal increase with

Options

  1. Adecrease of pressure
  2. Bincrease of temperature
  3. Cdecrease of atomic mass
  4. Ddecrease of temperature

Correct answer

D. decrease of temperature

Step-by-step 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.
