Best Answer

Yes, a stronger bond requires more energy to break, and also releases more energy when it is made. In a chemical reaction, if you are breaking strong bonds, and only making weak ones, the reaction will require a lot of energy (endothermic). If instead you are breaking weak bonds and making very strong ones in the products, the reaction will release energy (exothermic).

How is the strength of a covalent bond related to it's bond to its bond dissociation energy?

Greater the bond strength, greater is the bond dissociation energy. (So they are proportional to each other).

How is bond strength and bond energy related?

They are the same

How are bond energy and bond strength related?

Bond energy is a defined quantity, the amount of energy to convert 1 mole of compound into its constituent atoms, bond strength is not a strictly defined entity, it is sometimes used as a synonym for bond energy. Spectroscopists talk of bond strength and relate this to the resonant frequency of functional groups in say the IR/Raman spectra.Bond energy is the energy that is needed to break down one mole. Bond strength is the degree that is in a atom.

How is the stregth of a covalent bond related to its bond dissociation energy?

The strength of the bond increases as the bond dissociation energy increases.

How is polarity related to bond strength?

Polarity is related to bond strength because the bigger the difference in electronegativity, the higher the bond energy will be. This will then give rise to a much stronger bond.

What are bond energies and how to they relate to the stability of the bond?

Bond energies are the measure of strength of a chemical bond. The larger the bond energy, the stronger the bond.

How bond formation and bond breaking related to enthalpy?

Enthalpy is the measurement of total energy change of a reaction. The energy of bond formation and bond breaking can be used to calculate the bond enthalpy of the reaction. Bond enthalpy is the enthalphy change when 1 mol of bond is broken. Therefore the general equation to calculate the enthalpy change is energy of bond broken subtract by energy of bond formation.

What is the measure of the strength of a chemical bond called?

The strength of a chemical bond is equivalent to the energy that is released when that bond is formed, and that is called the heat of formation. It is measured in calories per mole.

What does a high dissociation energy say about the strength of a particular covalent bond?

That this bond is strong and needs a higher influx of energy to have disassociation happen.

How is the strength of a covalent bond related to its bond dissociation energy?

The energy needed to break one mole of bonds. A large bond dissociation energy corresponds to Strong covalent bond. They are unreactive partly because this dissociation energy for each of these bonds is high

What is the relationship between metallic bond strength and enthalpy of vaporization?

Metallic bond strength refers to the amount of energy as heat required to vaporize the metal. The enthalpy of vaporization is defined as the amount of energy absorbed as heat when a specified amount of substance vaporizes at constant pressure. Metallic bond strength increases as the enthalpy increases.

What are the two factors which affect the bond energy?

two factors that effect bond energy are polarity of molecule or compound and size of molecule

How does potential energy change when a chemical bond is formed?

potential energy decreases when bond is made, increases when broken

What are bond energies and how do they relate to stability of a bond?

Bond energy is a measure of the strength of a chemical bond, that is the amount of energy required to break a bond. The larger the bond energy, the stronger the bond. For covalent bonds, bond energies and bondlengths depend on many factors: electron afinities, sizes of atoms involved in the bond, differences in their electronegativity, and the overall structure of the molecule. There is a general trend in that the shorter the bondlength, the higher the bond energy and the stronger the bond.

Which property is best to use when determining the strength of an ionic bond in a solid?

What is Molar bond enthalpy?

Molar bond enthalpy shows the change in a bond association. For example, if one mole of bond is broken, the energy change that results is DHd (degree).

How does the energy of the bonded atoms change when a covalent bond is formed?

The energy of each o the bonded atoms decreases when such a bond is formed.

What type of energy is a measure of covalent bond strength?

Bond dissociation enthalpy (BDE) is a measure of how much energy is required for a bond to break in a molecule or compound. This can be quite low, e. a C-H bond, or extremely high, like a N-N triple bond, which needs almost 1000 kJ mol-1 of energy to break the bond.

What is the order of bond strength?

Order of bond strength from lowest to highest:Van der Waals

What energy change takes place when two atoms form a covalent bond?

they release energy!

Can bond order used to compare the strength of chemical bond?

yes. greater the bond order, greater the strength of the bond between the two atoms.
