How does temperature affect adsorption?

Here’s a explanation:

Effect of Temperature on Adsorption

1. Physical Adsorption (Physisorption):
   • Favored at low temperatures.
   • Reason: Weak forces hold the particles, and higher temperatures give them energy to escape.
   • Result: Increasing temperature decreases adsorption.
2. Chemical Adsorption (Chemisorption):
   • Favored at higher temperatures.
   • Reason: Formation of chemical bonds often needs energy to start the process.
   • Result: Increasing temperature can increase adsorption up to a point.

Simple tip:

• Physisorption → less at high T
• Chemisorption → more at moderate high T
