Endothermic reactions absorb a lot of energy. Exothermic reactions give off a lot of energy. Which type of reaction has a higher activation energy? Which one takes more energy to break up the bonds of the reactants?1.Exothermic reactions have a higher activation energy. Exothermic reactions require more energy to break up the bonds of the reactants.2.Exothermic reactions have a higher activation energy. Endothermic reactions require more energy to break up the bonds of the reactants.3.Endothermic reactions have a higher activation energy. Exothermic reactions require more energy to break up the bonds of the reactants.4.Endothermic reactions have a higher activation energy. Endothermic reactions require more energy to break up the bonds of the reactants.

In endothermic reactions, which are those that absorb energy, the activation energy is higher than in exothermic reactions, which are those that release energy. Also, Endothermic reactions require more energy to break up the bonds of the reactants.

Answer: 4.Endothermic reactions have a higher activation energy. Endothermic reactions require more energy to break up the bonds of the reactants.
