The total change in bond energy of the reaction is calculated by subtracting the sum of energies of bonds broken from that of bonds formed.
- An exothermic reaction will have a negative value while an endothermic reaction will have a positive for total change in bond energy.
<h3>How to calculate total change in bond energy from bond energies </h3>
To calculate the total change in bond energy of a given reaction, the following formula is used:
- Total change in bond energy = sum of energies of broken bonds - sum of energies of bonds formed
After getting the total change in bond energy of the reaction, the value obtained will be used to predict if the reaction is exothermic or endothermic.
A negative value indicates an exothermic reaction.
A positive value indicates an endothermic reaction.
Therefore, total change in bond energy of the reaction is calculated by subtracting the sum of energies of bonds broken from that of bonds formed.
An exothermic reaction will have a negative value while an endothermic reaction will have a positive for total change in bond energy.
