How catalyst effect activation energy
WebIt can be represented on an energy level diagram. The diagram shows that a catalyst provided a reaction pathway of lower activation energy . This makes more of the collisions successful at a given ... WebThe effect of a catalyst on the activation energy is shown on a chart called a reaction profile. This shows how the energy of the reactants and products change during a reaction.
