The adsorption isobar for chemical adsorption (chemisorption) plots the extent of adsorption () agai — Surface Chemistry Chemistry Question
Question
The adsorption isobar for chemical adsorption (chemisorption) plots the extent of adsorption ($x/m$) against absolute temperature ($T$). Which geometric shape best describes this isobar?
Answer: C
💡 Solution & Explanation
Chemisorption requires activation energy, so increasing temperature initially increases the rate of bond formation (adsorption increases). At very high temperatures, the thermal energy breaks the formed chemical bonds, causing desorption (adsorption decreases).
