WebAdult Education. Basic Education. High School Diploma. High School Equivalency. Career Technical Ed. English as 2nd Language. WebAug 13, 2024 · In endothermic reactions, the reactants have higher bond energy (stronger bonds) than the products. Strong bonds have lower potential energy than weak bonds. Hence, the energy of the reactants is lower than that of the products. This type of reaction is represented by an "uphill" energy-level diagram shown in Figure \(\PageIndex{2A}\).
