Introduction
• The bond dissociation enthalpy is the change in enthalpy when one mole of covalent bonds of a gaseous covalent compound is broken to form products in the gas phase.
Pre-Requisites:
Enthalpy, dissociation, bond
Activity:
Energy is required to break any substance e.g. a brick wall.
Real Life Question:
How do bonds break?
