Question

Is Bond Breaking Exothermic?

Answer 1

Exothermic reaction:

A reaction where energy is transferred to the surroundings from the system.

• The bonded atoms have less energy than isolated unbonded atoms.
• Because they are in a stable state due to the presence of bonds.
• The energy is released to reduce the energy or achieve greater stability.
• For breaking a bond energy is provided to the bonded atoms.
• They gain energy and break their bonds.
• The energy is mostly heat energy and light energy.
• Thus, breaking of bond is an endothermic process, not an exothermic process.
