In which reaction products have higher bond energy than the reactants?
In an endothermic reaction, the products are at a higher energy than the reactants. This means that the enthalpy change of the reaction (∆H) is positive.
Which has a greater bond energy?
Double bonds are higher energy bonds in comparison to a single bond (but not necessarily 2-fold higher). Triple bonds are even higher energy bonds than double and single bonds (but not necessarily 3-fold higher).
When the bonds of reactants have more energy than those of the products the reaction is endothermic?
2B. Energy is given off as reactants are converted to products. The energy given off is usually in the form of heat (although a few reactions give off energy as light)….Energy Diagrams.

|Heat is absorbed by reactants to form products.||Heat is released.|
Which CX bond has the highest energy?
This is because the halogens are more electronegative than Carbon apart from iodine. Fluorine is the most electronegative that pulls the electron pair strongly than the other halogens. Therefore, the Carbon-Fluorine bond is the strongest. 2.
Which compound has the highest bond energy?
Nitrogen molecule has highest bond energy due to presence of triple bond.
How does the total bond energy of the reactants compare to that of the products?
In endothermic reactions, the reactants have higher bond energy (stronger bonds) than the products. Strong bonds have lower potential energy than weak bonds. Hence, the energy of the reactants is lower than that of the products.
When the reactants have less enthalpy than the products?
In exothermic reactions, the products have less enthalpy than the reactants, and as a result, an exothermic reaction is said to have a negative enthalpy of reaction. This means that the energy required to break the bonds in the reactants is less than the energy released when new bonds form in the products.
Do bonds have energy?
Here is a surprisingly common answer: “The energy is stored in the chemical bonds. When you break the bonds, you get energy.”
