Define Bond Energy, Activation Energy

Differentiate between Breaking and Making Bond Energies. 

Bond Energy:

Energy needed to break different chemical bonds. 

This energy is called the bond energy.

Breaking Bond Energy:

Breaking bonds requires energy. 

It is endothermic.

Making Bond Energy:

Making new bonds gives out energy. 

It is exothermic.

Activation Energy:

The minimum energy required to cause a reaction to occur. 

The minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical change.
