alleryChemisorption needs a high energy of activation, so it is also called:
AReversible
BUniversal
CSpontaneous
DActivated
Answer & Solution
Correct answer: D. Activated
1. Forming a chemical bond needs an energy barrier to be crossed.
2. Chemisorption therefore involves a high activation energy.
3. It is often called activated adsorption for that reason.
