The adsorption of an inert gases on activated charcoal increase with
- A decrease of pressure
- B increase of temperature
- C decrease of atomic mass
- D decrease of temperature
Answer & Solution
Correct Answer
(D) decrease of temperature
Step-by-step Solution
Detailed explanation
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.
