According to the modern adsorption theory of heterogeneous catalysis occurring on a solid metal surf — Surface Chemistry Chemistry Question

💡 Solution & Explanation

In heterogeneous catalysis, reactants first adsorb onto the solid surface, react to form products via an activated complex, and then must desorb. Desorption removes the product molecules from the surface, freeing up the valuable active sites so that the catalytic cycle can continue with fresh reactant molecules.
