Endothermic reactions absorb a lot of energy. Exothermic reactions give off a lot of energy.

Question

Which type of reaction has a higher activation energy? Which one takes more energy to break up the bonds of the reactants?

Answer 1

Hi @Samado!!!!! Here are the answer to your questions. :)

Q1 answer - Exothermic reactions, however, have a lower activation energy compared to the reverse endothermic reaction. This is because there is a net energy release from an exothermic reaction because the products have less energy than the reactants.

Q2 answer - Endothermic reactions
