Reactions on surfaces
open-in-new
<p>Reactions on surfaces are reactions in which at least one of the steps of the <a href="/facts/Reaction_mechanism/9lanyVuy">reaction mechanism</a> is the <a href="/facts/Adsorption/ARH9peYM">adsorption</a> of one or more reactants. The mechanisms for these reactions, and the <a href="/facts/Rate_equation/VK18zUhN">rate equations</a> are of extreme importance for <a href="/facts/Heterogeneous_catalysis/ju7E0bab">heterogeneous catalysis</a>. Via <a href="/facts/Scanning_tunneling_microscopy/LQ4BzmwP">scanning tunneling microscopy</a>, it is possible to observe reactions at the solid gas interface in real space, if the time scale of the reaction is in the correct range. Reactions at the solid–gas interface are in some cases related to catalysis. </p>
