In an endothermic reaction.. A. the reactants are at a higher potential energy meaning it takes more energy to break the bonds of the reactants than is released when the bonds of the products are made. B. the reactants are at a higher potential energy meaning it takes less energy to break the bonds of the reactants than is released when the bonds of the products are made. C. the products are at a higher potential energy meaning it takes more energy to break the bonds of the reactants than is released when the bonds of the products are made. D. the products are at a higher potential energy meaning it takes less energy to break the bonds of the reactants than is released when the bonds of the products are made.
