An activation energy diagram for an endothermic reaction is illustrated here. The potential energy for products is higher than the energy for reactants. The magenta curve is the reaction pathway for an uncatalyzed reaction. The cyan (blue) curve shows what a catalyst does to the energy for the reaction path.
