Which fact must be true if a relationship is endothermic?(1 point)

Responses

The bond energy released by breaking the bonds in the reactants is greater than the bond energy used to form the products.
The bond energy released by breaking the bonds in the reactants is greater than the bond energy used to form the products.

More bond energy is absorbed on the reactant side than released on the product side.
More bond energy is absorbed on the reactant side than released on the product side.

More energy is needed to form the bonds on the product side than to form the bonds on the reactant side.
More energy is needed to form the bonds on the product side than to form the bonds on the reactant side.

The energy of each bond on the reactant side is greater than the energy of each bond on the product side.

In an endothermic reaction, the system absorbs heat from the surroundings. This implies that the overall energy required to break bonds in the reactants is greater than the energy released when new bonds are formed in the products.

Therefore, the statement that must be true if a relationship is endothermic is:

More bond energy is absorbed on the reactant side than released on the product side.

So the correct response is:

More bond energy is absorbed on the reactant side than released on the product side.
