Question

What causes chemical bonds to break?

Answer 1

• The main components of a chemical reaction are reactants and products.
• The bond between the atoms of the reactant molecule breaks due to the involvement of energy which is called bond dissociation energy.
• The bond dissociation energy is defined as the amount of energy needed to break the bond.
• When the reactant molecule breaks, the energy is released and the same energy is involved in the formation of product.
• Therefore, bond dissociation energy causes the chemical bonds to break.
