WebFeb 21, 2024 · The potential energy curve for the adsorption process is a representation of the variation of the energy (PE or E) of the system as a function of the distance ( d) of an adsorbate from a surface. Within this simple one-dimensional (1D) model, the only variable is the distance ( d) of the adsorbing molecule from the substrate surface. WebApr 2, 2005 · The red curve shows what a catalyst does to the activation energy and reaction path. The reaction has the same heat of reaction but a much lower activation energy. The catalyzed reaction would be much faster. NOTE: The energies of reactants and products have not changed. The heat of reaction is the same.
