The products have a higher bond energy than the reactants, and the difference in bond energy is absorbed from the surroundings. Photosynthesis is an endothermic reaction. ... Making and breaking chemical bonds are examples of 1. . Bonds are broken in the 2.
Answer:
Making and breaking of bonds are examples of chemical reaction. Chemical bonding is the process in which chemical bonds are formed and the process of breaking of bonds is called chemical dissociation.
It takes energy to break the chemical bond between the reactants and the making of new bonds gives the energy. Therefore breaking of bond is an endothermic process and making of bond is an exothermic process.
Bonds breaks when a particular amount of energy is given to it and this energy is called the bond energy.
