The change in bond energy is determined by subtracting the sum of energy of bonds formed from the sum of energy of bonds broken.

An endothermic reaction will have positive total change in bond energy while an exothermic reaction will have a negative value.

What is the total change in bond energy of a reaction?

The total change in bond energy or enthalpy change of a reaction is the amount of heat evolved or absorbed when reactant molecules react to form products.

To calculate the total change in bond energy of a reaction:

The sum of the energies of bonds broken is calculated
The sum of energies of bonds formed is calculated
The change in bond energy is determined by subtracting the sum of energy of bonds formed from the sum of energy of bonds broken.

A reaction is exothermic if the total change in bond energy is negative.

A reaction is endothermic if the total change in bond energy is positive.

Therefore, the change in bond energy is determined by subtracting the sum of energy of bonds formed from the sum of energy of bonds broken.

An endothermic reaction will have positive total change in bond energy while an exothermic reaction will have a negative value.
