Bond energy is the bond strength required to break and form the bonds of the chemicals. In the reaction, more energy was absorbed in the formation of the bonds. Thus, option A is correct.
What is an endothermic reaction?
An endothermic reaction is a chemical reaction that has lesser energy for the reactants compared to the products. The energy gets absorbed from the surroundings instead of getting released.
The bond energy required for the reactants' bond to be broken is higher than the energy required for the product's bond to be broken. This results in a lowering of the temperature of the system due to the cooling effect.
Therefore, option A. bond creation required more energy than breaking.
