|
Endothermic reactions ____
|
|
release more energy than they absorb
|
|
|
absorb more energy than they release
|
|
|
release and absorb exactly the same amount of energy
|
|
|
can either release more energy than they absorb or absorb more energy thanthey release, depending on the reaction
|
Explanation:
Detailed explanation-1: -In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products. If a chemical reaction absorbs as much energy as it releases, it is called isothermic-there is no net energy change.
Detailed explanation-2: -The total potential energy of the system increases for the endothermic reaction as the system absorbs energy from the surroundings. The total potential energy of the system decreases for the exothermic reaction as the system releases energy to the surroundings.
