Question

Which of the following statements is true?a) energy is released when bonds are broken because bond breaking is an endothermic process b) energy is required to break bonds because bond breaking is an endothermic process c) energy is released when bonds are broken because bond breaking is an exothermic processd) energy is required to break bonds because bond breaking is an exothermic process

Answer 1

b) energy is required to break bonds because bond breaking is an endothermic process.

Step-by-step explanation

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.

Hence, energy is required to break bonds. Energy is released when chemical bonds are formed because atoms become more stable. However, bond-forming is an exothermic process, because it releases energy.
