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 relationship between bond enthalpy and enthalpy of formation in chemical reactions?
The bond enthalpy is the energy required to break a specific bond in a molecule, while the enthalpy of formation is the energy released or absorbed when a compound is formed from its elements. In a chemical reaction, the bond enthalpies of the reactants and products determine the overall enthalpy change. The enthalpy of formation is related to bond enthalpies because it represents the sum of the bond energies in the reactants and products.
What is the difference between the bond enthalpy of the reactants and the bond enthalpy of the products in a chemical reaction?
The difference between the bond enthalpy of the reactants and the bond enthalpy of the products in a chemical reaction represents the energy change that occurs during the reaction. If the bond enthalpy of the products is lower than that of the reactants, it indicates that energy is released during the reaction, making it exothermic. Conversely, if the bond enthalpy of the products is higher than that of the reactants, it indicates that energy is absorbed during the reaction, making it endothermic.
How do the enthalpy of reaction bond energies compare to the enthalpy of formation in chemical reactions?
In chemical reactions, the enthalpy of reaction is the total energy change during the reaction, while bond energies are the energy needed to break or form specific bonds. The enthalpy of formation is the energy change when one mole of a compound is formed from its elements in their standard states. The enthalpy of reaction is influenced by bond energies, but it may not always directly correlate with the enthalpy of formation.
Why does bromine have lower bond enthalpy energy than chlorine?
Bromine has lower bond enthalpy energy than chlorine because bromine has larger atoms with more electron shielding, which results in weaker bonding forces. Additionally, bromine has a longer bond length compared to chlorine, which contributes to a lower bond enthalpy energy.

Bond enthalpy is always?
Bond enthalpy is the energy required to break one mole of a specific bond in a compound. It is always a positive value as energy is needed to break bonds.
Is bond enthalpy and energy needed for bond formation is same for all the compounds?
no

What is the relationship between enthalpy of atomisation of hydrogen and the bond dissociation enthalpy of the H-H bond?
the enthalpy of atomisation of hydrogen is equal and (in principle) identical to the bond dissociation enthalpy of the H-H bond. However, IF the first is measured by calorimetry and the second by spectrometry there might be a systematic difference.
How can one calculate enthalpy using bond energies?
To calculate enthalpy using bond energies, you need to subtract the total energy needed to break the bonds in the reactants from the total energy released when the new bonds form in the products. This energy difference represents the change in enthalpy for the reaction.
How to calculate bond energy using enthalpy?
To calculate bond energy using enthalpy, you can use the equation: H (bond energies of bonds broken) - (bond energies of bonds formed). This equation involves subtracting the total energy needed to break the bonds from the total energy released when new bonds are formed. Bond energy is the amount of energy required to break a specific bond in a molecule.
Lattice energy is effected by all the following factors except what charge of ion size of ion or number of electrons shared in the chemical bond?
Number of electrons shared in the chemical bond. Lattice energy is affected by the charge of the ions and the size of the ions, as these factors determine the strength of the electrostatic interactions within the lattice structure. The number of electrons shared in the chemical bond is not directly related to lattice energy, as lattice energy is primarily influenced by the arrangement of ions in the crystal lattice.
Why is the formation of ionic compound exothermic?
Look at the problem from the other angle why does it take energy to break up an ionic lattice. It is because of the electrostatic attrction of the ions which has to be overcome. A measure of the is energy is the lattice enthalpy which depends on the charges, th einterionic distances and the geometry of the lattice.
