WebCatalysts do not appear in the overall chemical equation for a reaction. How catalysts work A catalyst provides an alternative reaction pathway that has a lower activation energy … WebA catalyst does not lower the activation energy. Instead, it bypasses the barrier by offering a lower-energy alternative . So instead of needing a lot of energy to get to a highly energetic transition state before the reaction can proceed, a molecule can have its transition state stabilized by a catalyst, offering a reaction route that requires ...
