Adsorption and Catalysis — Chapter Summary

Adsorption is the process in

Adsorption is the process in which molecules of a gas or solute are attracted and retained on the surface of a solid. The substance being adsorbed is

Physical adsorption occurs due to weak

Physical adsorption occurs due to weak van der Waals forces and is reversible, multilayered, and occurs at low temperatures. Chemisorption involves st

Freundlich isotherm describes adsorption mathematically as

Freundlich isotherm describes adsorption mathematically as x/m = k/p^n, valid at moderate pressures. Langmuir isotherm assumes monolayer adsorption an

A catalyst increases the rate

A catalyst increases the rate of a chemical reaction without being consumed. It works by lowering the activation energy through an alternative reactio

In homogeneous catalysis

In homogeneous catalysis, the catalyst is in the same phase as the reactants (e.g., H⁺ in solution). In heterogeneous catalysis, the catalyst is in a
